This article reviews the Garmin Nuvi 770 satellite navigation system, which is at the higher end of the Garmin Nuvi range.
If you compare it to the likes of the Nuvi 250W it is quite a bit more expensive. So what extras do you get and is it worth the extra money? This review will try to help you decide.
The Nuvi 770 is identical to the Nuvi 760 except it has transatlantic maps covering both Europe and North America, whereas the Nuvi 760 just has European mapping. If you don’t need the North American maps then go for the Nuvi 760, it is about £30-40 cheaper.
In a nutshell the Nuvi 770 offers the following features not seen on the Nuvi 250W:
- TMC Traffic Module to help avoid traffic congestion and road blocks
- Bluetooth support so you can make hands free calls on your mobile phone via the Nuvi 770
- FM Transmitter so voice directions and MP3 audio can be heard through your car stereo speakers
- Transatlantic maps of Europe and North America (250W has just Europe)
- Multiple destination routing, which includes automatic sorting to provide an efficient route for things like deliveries or sales calls
- Trip log which records where you’ve been on the map
- Marking of your last position when the unit is turned off (useful if your car is parked in a huge car park such as an amusement park or shopping mall and you can’t remember where the car is parked)
- “Where am I” feature that gives your current location, nearest address, nearest intersection, along with quick access to Points of Interest (POIs) for the nearest hospitals, police stations and fuel stations
- MP3 player
All of these features will be covered in more detail later in this article.

First Thoughts
The Nuvi 770 looks pretty much like the Nuvi 250W. It has the same great looks and easy to operate user interface. The wide screen plus the slim and compact looks make it a pleasure to use.
A USB cable is included, something that was missing from the 250W. You also get a leather carry case, very useful for an expensive sat nav system like this. The carry case will easily fit in a coat or jacket pocket.
The quick user manual covers most of the information you need to get started. I personally would have preferred a bit more information in the manual, especially regarding how to configure the various settings. You can though download a full user manual from the Garmin web site which covers everything in far more detail.
GPS Signal
GPS reception has always been excellent across the Nuvi range and the 770 is no different. A satellite signal was established in around 1 minute the first time it was switched on, this was standing inside a building.
Some sat nav systems require you to stand outside for ages before an initial signal is established, which can be a bit of a pain, so it is nice to see a system work out of the box with no fuss.
If your inside a building and a GPS signal cannot be found then it will prompt you whether to continue searching for a satellite signal. If you say ‘No’ then it switches to ‘Indoor’ mode. This is a good idea. It means the Nuvi won’t waste battery power trying to continually find a GPS signal.
Maps
The Nuvi 770 includes full coverage of UK, Europe and North America, right down to individual street level. If you spend a lot of time driving around both Europe and North America then you will welcome this coverage.
Navigation
All the normal navigation features you would expect from a sat nav system are supported, such as being able to plan routes by the fastest or shortest route. There are also options to plan journeys by bicycle or pedestrian routes on foot. There is also an ‘Off Road’ mode which provides point-to-point routes without regard for roads.
Full postal code entry is supported. Alternatively. if you don’t know the postal code then you can spell the city, street name and house number. If you want to navigate to a particular Point of Interest (POI) such as a food outlet, fuel station or car park then you can do that too.
By default it will search for POI near your current location, but you can also specify to search for POI near a different city. This can be useful if you need to find a hotel or restaurant near your destination.
The Nuvi 770 stores a list of recent destinations and you can also save your favourite destinations for easy access later. You can also save your home address if required. If you want to navigate to a set of co-ordinates you can do that too.
The Nuvi 770 also supports multiple destination routing. You can enter multiple destinations and the Nuvi will automatically sort them into the most appropriate order. This can be useful for things like deliveries or sales calls.
If you take a detour or wrong turn whilst travelling then the Nuvi 770 will automatically recalculate the route and get you back on track. I tested this feature several times and it worked fine.
The following image shows the main map screen.
The maps are clearly laid out and easy to read. At the top of each map is a green text bar. If you press this then it will display the route in text only mode. This can be useful for seeing the next few turns on your journey. You can scroll through your entire journey this way if needed. You might want to do this for example to find a complicated step on your route.
At the bottom left of the map is a trip information button which displays the estimated arrival time. If you’re just driving around without a route planned then this button displays the current speed. If you press this button then the trip log is displayed, displaying information such as total journey time, maximum speed and average speed.
At the bottom right of each map is the turn button. If you press this button it will display the Turn Page which shows in more detail the next step of your journey.
This is basically a combination of the map view and text view on one screen which can be useful at times. If you’re just driving around without a route planned then the turn button displays your current direction.
The Nuvi 770 also supports a simulator mode. If you plan a journey indoors where there is no satellite signal then you have the option for the Nuvi to simulate the journey for you. Bear in mind though that this will get tedious for a long journey.
In my tests I used the Nuvi 770 on cross-country trips from Wiltshire down to the South coast, and also urban driving along the M4 corridor.
The voice directions include not only the road numbers, for example “Turn left in 300 yards onto the A4”, but also street names, for example “Turn left in 300 yards onto Western Avenue”. This is the first system I’ve tested which has both road numbers and street names included. On the whole it worked pretty well. The voice sometimes sounds a little digital (computer-like) if that makes sense, but overall I found the pronunciation of street names quite acceptable.
The use of street names extends to your favourite destinations too. If you save a favourite destination and call it “Uncle Jacks”, then the Nuvi 770 will include that in the voice directions, for example “Arriving at Uncle Jacks on left”. Quite clever really.
On the whole the system performed very well, getting me to my destination every time without any problems. The routes selected by the Nuvi 770 were OK, but they were not always the routes I personally would have chosen.
The Nuvi sat nav systems only offer you the option of either using the fastest or shortest route. I personally would have liked to have seen a couple more route profiles. The Sony nav-u systems for example offer an optimum route profile which uses a combination of fastest or shortest route if it offers a reasonable savings in journey time.
The mapping software on the whole is very accurate, although I did come across a couple of odd things which were probably down to the particular road I was driving along. On one occasion the map failed to detect that I needed to turn left at a T-junction (it thought it was just one continuous road), and on another occasion it kept saying “recalculating” for about one minute, almost like the road I was on didn’t exist. I was driving along cross-country routes at the time but it just goes to show that not every sat nav system has perfect mapping software, even expensive models like this one.
This wouldn’t put me off buying one of these. Every sat nav system I’ve tested has some minor quirks, but they’re all normally good at getting you to your destination. It’s just when you consider the price tag for the Nuvi 770 you expect a system like this to be almost perfect.
Pedestrian and Off-Road Navigation
The Nuvi 770 can be used in predestrian mode. From the main screen select Tools –> Settings –> System and set the Usage Mode to Pedestrian.
You need to set the routing profile depending on where you intend to walk. From the main screen select Tools –> Settings –> Navigation and choose the appropriate Route Preference.
If you plan to walk just along roads and streets then use either the ‘Shorter Distance’ or ‘Faster Time’ route profile. This can be great for walking on foot in large towns and cities.
If you want to walk wherever like, regardless of whether there are any roads, such as across a field for example, then use the ‘Off Road’ route profile. The Nuvi 770 can also remember where you parked the car. If you’ve parked your car in a huge car park, such as those at an amusement park or mega mall, and you’ve forgotten where you parked, then you can use the pedestrian off-road mode to find your car.
In my tests the pedestrian mode worked a treat, it will even tell you how fast you’re walking.
Screen
The widescreen is just like the other Nuvi widescreen models and is equally impressive. Garmin have put some thought into the usability of the device and this can be seen with the on screen controls which are clear and easy to read. The screen is easy to read both at day and night and I didn’t observe any problems with screen glare.
Volume
The volume level can be adjusted from the main screen, but it does not offer automatic volume adjustment depending on the speed you’re travelling. Some systems for example will increase the volume when driving at high speeds so you can still hear the voice directions.
I found the speaker on the Nuvi 770 fine and didn’t find this an issue. I set the volume to around 80% and that worked pretty well.
Bluetooth
The Nuvi 770 can be paired up with a bluetooth phone. This can be useful for making hands free calls via your Nuvi. The Nuvi 770 will automatically download your phone address book. You can then start making and receiving phone calls via the Nuvi 770, you can even send and receive SMS text messages.
Here is an example of scrolling through the phone book, the image shows the O2 contacts from my mobile phone downloaded by the Nuvi.
Just like any bluetooth device, you need to make sure your mobile phone is reasonably close to the Nuvi 770. Garmin recommend that your mobile phone is no more than 10 meters away from the Nuvi, that distance should be fine for most vehicles.
I found the bluetooth feature worked very well. I recommend you set the Nuvi volume level to around 70%, any louder than that and the person at the other end of the phone will likely get some feedback, plus their voice will sound too loud on the Nuvi speakers.
I tested out both the phone and SMS features from the Nuvi and it worked perfectly every time. My only complaint was that I could not get voice dialling to work. If your mobile phone supports voice dialling then you should be able to phone someone by just speaking their name into the Nuvi, but I never got this feature to work. This may have been down to my phone but after about half an hour trying I gave up.
A nice feature I liked is the ability to dial a Point of Interest (POI) such as a restaurant. Simply search for the POI on the map and then touch the dial icon to make the call.
If you want to store your home phone number so you can quickly call home then you can do that too. Personally I never used this feature since I already had my home phone number stored in my phone address book.
TMC
The Nuvi 770 comes with a free lifetime traffic subscription provided by TrafficMaster. I’ve tested out TMC before on the Sony nav-u range and found TMC reception patchy, for example it was non-existent where I live. I was therefore pleasantly surprised to find the Nuvi 770 working far better in this department. I can even get a TMC signal at home, something I never could with the Sony range.
The following map shows the TMC coverage you can expect.
The TMC antenna is attached to the vehicle power cable which isn’t a bad idea, as it is one less thing to possibly lose when carrying all the equipment around.
Garmin in my opinion though haven’t put much though into the usability aspects on TMC reception. In order to ascertain whether you have a TMC signal, you need to look at the connector that plugs into your cigarette lighter socket. The connector has an LED light which indicates if a TMC signal is available. A green light indicates TMC is being received and a red light indicates no TMC signal.
In order to see this light you need to take your eyes completely off the road which in my opinion is dangerous. Garmin really should have displayed an icon on the screen to show if TMC was available, like other sat nav systems do.
If there is a traffic problem ahead then the Nuvi 770 will display an icon indicating the problem, these icons cover the following categories: road construction, road closed, slow traffic, accident, incident and travel information.
The TMC traffic icons are also displayed on the map when not navigating a route. This can be useful when you’re driving along familiar routes and just want a warning of any hold-ups ahead.
If you’re navigating to a destination then it also displays an estimate of how how much time has been added to your journey as a result of any delays.
When calculating the route the Nuvi will examine any traffic problems on your route and optimizes for the shortest route. You may end up still being routed through a traffic problem if no sensible alternative exists. If the delay is severe enough though it will recalculate the route.
In my tests so far I’ve found the TMC signal to be excellent. I’ve used the Nuvi 770 along the M4 corridor and had no problems at all. I’ve yet to encounter any traffic problems in testing so far, so I have been unable to review how accurate the traffic information is, but I will update this review later once I find out.
FM Transmitter
The Nuvi includes a wireless FM transmitter which allows voice directions to be broadcast through your FM car stereo instead of the Nuvi 770 speakers. You can also use this feature to playback MP3 files stored on the Nuvi too.
The important part is selecting the right FM frequency to use. You need to choose a frequency not used by any other radio stations in your area, otherwise you get too much interference. So you need to use a bit of trial and error before you get a decent result.
You can either manually choose an FM frequency for the Nuvi to broadcast on, or you can let the TMC traffic receiver select a frequency automatically for you. I let the Nuvi automatically choose a frequency for me. The first frequency it selected was too close to the same frequency used by Radio 2 which meant too much interference, so I had to let the Nuvi choose another frequency about 5 times before I was happy with the results.
Even when I had selected a decent FM frequency with no interference, the voice instructions didn’t sound as good on my car stereo speakers as they do when coming through the speakers on the Nuvi. I need to experiment more with the FM transmitter but so far I’m not a huge fan of it.
The other thing to remember, you may select a decent FM frequency for the Nuvi to use at home, but once you drive further afield you may enter a region where another radio station broadcasts close to the same FM frequency used by the Nuvi, which means you would need to re-tune the Nuvi to use another frequency. This is not going to be practical if you’re driving through a part of the country you’re not familiar with. The last thing you want is to not hear the voice instructions whilst driving due to radio interference.
I think there is more potential for success with manual tuning. Selecting a frequency right at the beginning of the FM frequency band may be more successful, such as 88FM or lower. But even that is not guaranteed to give success.
Safety Cameras
The Nuvi 770 comes with speed camera warnings out-of-the-box. In my tests I found the speed cameras worked well. It detected both fixed and mobile safety cameras. It also detected average speed cameras like the ones you see in motorway roadworks.
When approaching a safety camera the Nuvi 770 will issue a warning sound and display a text warning on the map.
The Nuvi will also detect safety cameras when not navigating a route. This can be useful when you’re driving along familiar roads and just want to switch the Nuvi on and use it as a speed camera detector. I tested this out along the M4 and it worked fine.
You may want to consider updating the safety camera information every year or so, to keep up with any new safety cameras being put up. You can do this by purchasing a new subscription from Garmin. It currently costs £30 (40 Euros) which in my opinion is expensive.
For a much cheaper alternative you can try looking at the following link:
Speed camera plugin for Garmin.
Windscreen Mount
The windscreen mount is just like the others in the Garmin range. I have always liked the design used by Garmin. It is very easy to use with few moving parts so little to go wrong. You simply press the suction cup against the windscreen and then press the lever to apply the suction.
The Nuvi cradle then snaps onto the suction cup using a ball and socket mechanism which allows you to twist and turn the Nuvi into whatever position you like. The Nuvi clicks onto the cradle with little effort and is held securely. To detach the Nuvi from the cradle you simply press the release button on the cradle and pull the Nuvi away.
Garmin also include a dashboard disk if you want to attach the Nuvi to the dashboard, but be warned, the dashboard disk uses semi-permanent adhesive when attached and will be very difficult to remove later.
System Tools
If you press the tools (wrench) icon on the main screen there are a large selection of options that can be viewed and customized. These are outlined below.
Where Am I?
Press this button and it will show your current location as a set of co-ordinates, including current elevation. It also displays the nearest address and nearest junction. There are also quick launch icons to show the nearest hospitals, police stations and fuel outlets. You also have the option to save your current location so you can navigate to it later.
Unit Converter
Use this tool to convert any unit of measurement, such as area, distance, speed, temperature, volume and weight.
Currency Converter
Use this tool to convert from one currency to another.
Calculator
Provides a simple calculator interface for performing quick addition, subtraction, multiplication and division.
Language Guide
The Nuvi 770 comes with a sample of the Garmin Language Guide. These guides contain common words and phrases, such as ordering food in a restaurant or asking directions in a foreign language. You can get the Nuvi to speak these phrases aloud. This can be useful if you’re travelling around Europe and don’t speak the local language.
It also includes bilingual dictionaries so you can quickly convert a word from English to Spanish, German, French, Italian or Portuguese. You can also convert the other way, such as Spanish to English.
World Clock
This tool will show your current time, plus 3 other time zones. You can also display a world map showing which regions in the world are currently in daylight and nighttime.
My Data
This screen quickly allows you to set your home location, delete your favourites and clear the trip log.
Routes
The Nuvi 770 allows you to store up to 10 routes. This screen allows you to view all your saved routes.
Picture Viewer
Use this tool to view pictures you’ve uploaded to the Nuvi. You can scroll through each photo, show each photo full screen or do a slide show. You also have the option to display one of these pictures when you power on the Nuvi 770 if you don’t like the default Garmin logo.
Media Player
You can upload MP3 files to your Nuvi and then play them back through the built-in media player. The media player also supports audio books which you can purchase and upload to the Nuvi. Copying the MP3 files to the Nuvi is straightforward. The Nuvi appears as an additional hard drive when connected to your computer. You simply copy the MP3 files to any folder you like on the Nuvi.
Help
If you’re stuck with any aspect of the device then use the help screen to get help information displayed on the screen. If you don’t have access to the online manuals, such as out in the open somewhere, then this screen can come in useful.
Settings
This screen allows you to customize a huge selection of settings.
System
Here you can set the unit of measurement, miles or kilometers,the usage mode – automobile, bicycle or pedestrian, keyboard layout – ABCDE or qwerty, and GPS simulator on or off.
Navigation
Here you can set the route preference – fastest time, shortest route or off-road, and avoidances – U-Turns, major roads, toll roads, traffic problems, ferries, car share lanes and unpaved roads.
Display
Use this option to set the colour mode – automatic, daytime or night-time. Enable or disable the screenshot facility and set the brightness.
Time
Set the clock to either a 12 or 24 hour format, set the time zone and enable or disable daylight saving.
Language
You can set the voice, text and keyboard to a large selection of languages from around the world. In the UK the Nuvi 770 comes with a female voice.
Map
Set the level of detail displayed on the map, the map view – track up, North up or 3D, the vehicle icon, and hide or show the trip log. You can also view the map info which shows which maps are loaded on the Garmin.
Security
Use this screen to enable either the Garmin lock or safe mode.
Bluetooth
This screen allows you to manage your bluetooth connections.
Volume
You can set individual volume limits for both voice directions and the media player from this screen. There is also an option to enable the FM transmitter from this screen.
Proximity Points
This screen allows you to disable the safety camera feature should you wish to do so.
Points of Interest (POI)
The Nuvi 770 has a massive POI database, just like the other Nuvi range. You won’t be disappointed in this department.
The following POI categories are supported: food, fuel, transit, lodging, shopping, bank/ATM, parking, entertainment, recreation, attractions, hospitals, community and auto services.
For many of these categories you can then refine your search further. If you search for entertainment for example, you can limit the search to sub-categories like bars, cinemas, theatres, etc.
If you use the “Where Am I” feature mentioned earlier you can also search for nearby police stations. If the POI you are looking for doesn’t fit into one of these categories then you can just spell the name.
By default the Nuvi will search for POI near your current location, but you can also search for POI in any other city you like.
If you’re already navigating to a destination then you can ask the Nuvi to search for POI along your current route or near your destination. This can be useful if you want to find a hotel or fuel station for example near your destination.
You can update the POI database on the Nuvi by using this link:
Garmin POI loader.
Summary
The Nuvi 770 is a top notch sat nav system. It looks good, has easy to use on screen controls, has a huge POI database and the TMC reception is the best I’ve tested so far on a sat nav system. The speed camera and bluetooth features worked impressively well too.
The Nuvi includes transatlantic maps, meaning you can use this system in both Europe and North America straight out of the box. If you’re a frequent visitor to both sides of the Atlantic you’ll welcome this. If you don’t need the North American maps then save yourself some money and go for the Nuvi 760, which is identical in spec but just has European maps.
All these features do come at a price though. There are systems half this price that will perform just as well getting you to your destination. If you’re the type of person who likes top of the range models with lots of features then there is very little to complain about.
I’m not convinced the FM transmitter is a useful feature, and in my tests it didn’t perform very well. When you consider the price tag I think the Nuvi 770 is a little overpriced, but if you’ve got the money you won’t be disappointed. The Nuvi 770 really is a superb unit.
Pros
- Wide screen
- Strong GPS signal
- Easy to use touch screen controls
- Speed cameras warnings out-of-the-box
- TMC signal excellent
- Voice directions include road numbers and street names
- Huge POI database
- Full map coverage of Europe and North America
Cons
- Expensive
- FM Transmitter not as good as I was expecting

Hi Ronald,
If you can tell us your budget and what features you definitely need then we can offer some general advice.
6 A Williamson // Apr 20, 2008 at 8:50 am
Thanks for a grerat review. I noticed that you can offer advice on which Sat Nav to buy and was wondering if you could do the same for me. I need the coverage of the Nuvi 770 and wondered if there are any better ones. I’m not too bothered about the bluetooth features, or FM transmitter but I would like the pedestrian feature. Is it also possible to preload your route from a PC so you don’t end up going down alsorts of country lanes?
7 Dean // Apr 20, 2008 at 7:23 pm
It depends on your budget. If you don’t need maps of North America then you can save about £40 and go for the Nuvi 760 which covers the UK and Europe. Both the 760 and 770 are great systems at around £220 and £260 respectively on Amazon. If you’ve got the money there is little to complain about either system.
If you want to keep under £200 for your budget there are a few options.
There is the Nuvi 250W. It has been around a while and is still very popular with readers. It has full European mapping and is around £130 on Amazon. It does not have the TMC traffic module though, and it doesn’t have text to speech (i.e. voice directions don’t read out the street names).
There is also the new Nuvi 255W which is due for release May 2008 which builds on the success of the 250W. The 255W includes several of the features seen on the Nuvi 760/770 like text to speech and the “Where Am I” feature.
I think the pedestrian feature is standard across the whole Nuvi range.
Do you want your sat nav to include the TMC traffic warnings?
8 riof // Apr 24, 2008 at 7:57 pm
I’ve just bought one of these & it’s great except for one thing. Bluetooth will not enable. I have updated to the latest software & bluetooth firmware but the screen ‘hangs’ with the message “enabling bluetooth” permanently displaying. It just will not work. I have to reset the Nuvi to restore operation & I can’t seem to get a response from Garmin. If I can’t get a resolution soon it’ll have to go back to Amazon. I’ve heard others are having problems with this. Can anyone get some feedback from Garmin ?
9 Dean // Apr 24, 2008 at 9:35 pm
I had the same problem on a Nuvi 660 which had to go back. No problems with my 770 though. Have you tried phoning Garmin?
10 riof // Apr 24, 2008 at 10:05 pm
Tried once but had to hold for too long. Aiming to call them tomorrow (Friday 25th April).
11 riof // Apr 25, 2008 at 10:22 pm
OK. Managed to get hold of Garmin support. They sent me some new files in the folder RemoteSW. Transferred these to the nuvi then ran the Garmin WebUpdater which picked up the latest bluetooth firmware (again !). Downloaded & installed ok but bluetooth still won’t work. In fact it’s got worse. Now it locks up when disabling the non-enabled bluetooth as well as locking up when enabling the disabled bluetooth if you can follow. Have relayed this to Garmin & waiting for a response.
12 riof // Apr 27, 2008 at 10:57 pm
Garmin say it needs to be returned to them for repair. Well I know my statutory rights so I’m returning it to Amazon for a replacement as it’s faulty. Will I be able to transfer my safety camera subscription to the replacement nuvi, will the bluetooth work, will I be able to navigate using A-Z paper technology again.
Stay tooned, same time, same channel
… _ _ _ … …. . . _ .. ._ _ .
13 riof // May 1, 2008 at 10:21 pm
Replacement nuvi 770 from Amazon received ok. Bluetooth works fine. Safety camera subscription transferred to new nuvi. Very good customer service from Amazon & Garmin.
14 Dean // May 2, 2008 at 8:18 am
Glad you got the problems sorted out.
15 Erik Neipper // May 9, 2008 at 7:56 am
Thanks for your excellent review. I am thinking of buying either the Nüvi 760FM or the 770 with preinstalled Europe city navigator . I am also planing to take a trip to Australia, and I would like to know if I can buy and install Australian maps in either of these two models?
16 Alex // May 11, 2008 at 2:09 am
Great review, very informative.
Do you know if there is a POI database that can be downloaded that contains information about low bridges? This would be very useful for LGV drivers. Or is this already included in the supplied POI database? Also, is it possible to get a 24v adapter?
17 Alex // May 11, 2008 at 4:07 pm
Just to answer my own question, yes there are low bridge POIs available. I bought the GPS unit today. First impressions are that it’s a great unit. I find the sound quality to be barely acceptable though – not loud enough and a bit “tinny”, especially with directions as opposed to telephone calls. FM reception through my radio was patchy and poor. Otherwise it is a great, easy to use unit.
18 Dean // May 20, 2008 at 9:07 am
Erik,
Yes you can buy Australian maps for both the Nuvi 760 and 770. Have a look at the following link:
http://www8.garmin.com/cartography/ontheRoad/
You can buy an SD card with the Australian maps preloaded.
19 Pierre // Jun 1, 2008 at 5:58 pm
A brilliant review that is to the point without all the usual waffle and unnecessay complicated jargon. Well done and thank you.
20 Dean // Jun 4, 2008 at 8:10 am
Thanks Pierre. Glad you enjoyed reading the review.

Hi. I purchased a Nuvi 770 yesterday. When I switched it on the maps were locked and so was the bluetooth. Also The POI werent there. I contacted Garmin who gave me a fix. It worked to unlock the maps but not the bluetooth. Then after contacting them again they gave me a fix for the Bluetooyh which didnt work. I returned it today to my retailer who was great and replaced it. Guess what. I turned on the replacement and everything worked great………for a couple of hours and bingo exactly the same thing happened. Maps and bluetooth are locked. Can someone recommend another device with the same or better spec that will actually stay working? Please Help. This thing has stressed me
22 Dean // Jun 18, 2008 at 9:56 pm
Stephen,
Perhaps the supplier has a few duff models in their store? The Nuvi 770 has worked fine for me. Perhaps you could try another supplier.
If you don’t need North American maps then try the Nuvi 760, it is identical to the 770 in every other respect and is cheaper too
23 riof // Jun 18, 2008 at 10:58 pm
Stephen,
As an update to my previous comments, my replacement 770 worked fine for about four weeks then the maps locked again & the Bluetooth stopped working as before. I unlocked the maps by pasting in the unlock codes from Garmin but I have given up on the Bluetooth altogether. Garmin say a fix will come from the States but I can no longer recommend this product if you want Bluetooth to work reliably. I am a trifle pissed off.
24 Dean // Jun 19, 2008 at 8:34 am
I had the same bluetooth issue on a Nuvi 660 I reviewed a while back. I’ve found a few other people reporting this issue by searching on the web.
I found these instructions for resetting the bluetooth. It sounds like you’ve tried this already but posting here in case anyone else finds it useful:
“You may need to reset your BlueTooth:
1) From the Nuvi main “Where To?” screen, tap “View map”
2) On the map screen, tap the “speed” indicator in the lower left corner of the screen.
3) On the next screen, there is a large round speedometer (mph) near the top center of the screen. Press and hold on the center of the speedometer until the screen changes to a diagnostic mode that says “Shutdowns” at the top.
4) Press “Next”at the bottom of the screen repetitively until you come to a screen that says “Bluetooth status” at the top…
5) On the Bluetooth Status screen, press “Updt PR” button in the lower right corner. The screen should show “Do you really want to update the Bluetooth firmware?”… Press “yes”… Let the unit sit for several minutes. It should show “Updating Bluetooth on the screen. When it is complete, it will return to the “Bluetooth Status screen…. Press “Quit” in the lower left corner… Then return to the main “Where To?”
screen and try enabling and paring the Bluetooth again?.
Additionally, it is best to pair the devices from the cell phones menus and pairing procedures, instead of from the Garmin device……
Note: before re-pairing the Nuvi to your cell phone, make sure you remove the nuvi device from your cell phone first, then add device. If your nuvi bluetooth still fails after you do this step, then your nuvi bluetooth file maybe corrupted. You will need to download this file and reinstall it to your Nuvi”
25 riof // Jun 22, 2008 at 11:03 am
Dean, thanks for the secret. I thought you might have found the answer for me but alas, alack, it didn’t work. After pressing Updt PR, nothing happens. I left it for an hour or to & tried it over a few days but to no avail. I even trashed the RemoteSW file to prompt WebUpdater to download the latest Bluetooth Firmware but it just won’t play ball & update the firmware. I have a large mallet in the shed. Do you think this might be worth a try?
26 Errol Stagg // Jun 22, 2008 at 1:30 pm
Your reviews are very comprehensive and interesting. I would like to buy a 255W. Can you tell me if there is an automatic “zoom in” when making a turn at a road junction? This was a very useful function on an old Tom Tom I had.
27 Dean // Jun 22, 2008 at 9:50 pm
Not sure about the automatic zoom. I haven’t got a 255W to test this out on. I do have a Nuvi 770 so will give that a go later this week and report back.
I presume what you want to do is manually zoom out to see more of the map, but then get the sat nav to zoom in automatically when approaching a junction.
28 Khan Ikram // Jul 6, 2008 at 7:10 pm
It is very helpfull note that you published. Thanks a lot for this information.
29 Bill Bertham // Jul 16, 2008 at 2:04 pm
Thank you for a very clear revue. I loved the plain language explanations. Something the manufactures should pick up on.
My 770 works well and I have had no problems with the FM transmission. I could never figure out how to use the self selection of the channels, so I have not bothered too much with this feature. There are a number of things that I find very frustrating, Not all of the post codes or even towns are available through the programming, when I try to spell them out i.e. Ammanford (in Wales), can’t get the post code SA18 1AR although both have been there for years! When I try to revert to spelling it, after I have put in a few letters Garmin then gives me a list that it thinks I am looking for, and guess what Ammanford is not on it. Now, it’s only because I know where it is that I can go onto the map find it and then opt for navigate there. If I did not know where it was I would be totally stuck. I asked Garmin help desk about this and their only response was “You will have to find another way of putting it in”! I have found this problem on one or two places.
Apart from this I am happy with the performance.
30 ken hatch // Aug 5, 2008 at 4:09 pm
I have a nuvi 760 evry thing works well but the volume for every thing seems to low especialy the traffic alerts
31 Dean // Aug 5, 2008 at 6:18 pm
Is it still too quiet when the volume is set to the maximum level?
32 ken hatch // Aug 5, 2008 at 9:15 pm
yes even when it is on 100% volume
regards ken hatch
33 Dean // Aug 5, 2008 at 10:07 pm
Ken,
Not sure what to suggest. I’ve not run into that problem on the Nuvi 770. If you’re technically minded it may be possible to edit the .VPM file on the Nuvi 760 for the British Emily voice and set the volume to a higher level. You could try searching around on Google for more details.
34 noel // Sep 24, 2008 at 9:46 am
I just bought a Garmin nuvi 770 in the States and it worked fine for a week, bluetooth and all. Then one day I switched it on and it was asking for the screen to be recalibrated and after all that the maps were locked. I registered the unit, updated the firmware, got the unlock codes and the maps are fine. But then when I went to enable bluetooth I got the same problem as above, it hangs on ‘Enabling Bluetooth’. There is no more firmware to update using the webupdater and I’ve tried the various suggested fixes, but all to no avail. UpdtPR – nothing – it doesn’t seem to try to do anything, just returns to the Bluetooth status screen. Some suggest removing a .GCD file and updating the firmware again – but again (1) there is no separate bluetooth firmware listed and (2) reinstalling whatever firmware is available does nothing. Given it worked once, I reckon it’s a software/firmware problem that Garmin will eventually provide – seeing as how so many people are reporting this problem and returning their units. If anyone does come across a sure fix for this, I’d appreciate it. How can there be so many units with so many problems and Garmin are getting away with it?
35 Dean // Sep 24, 2008 at 6:04 pm
I’ve seen this issue on the Nuvi 660 before but this is the first I’ve heard about it on the 700 series. Have you spoken to Garmin technical support?
36 noel // Sep 24, 2008 at 6:11 pm
Yes, they helped me out with the inital map unlocking – why it happened in the first place is another story – who knows? But as for the Enabling Bluetooth problem after that, they suggested the UpdtPR route, but that did nothing. They also asked to make sure my firmware was up to date which I made sure with WebUpdater, but said if neither of these work to return it. I’m not going to return anytime soon, I’ll keep trying for a solution first, but alas, none are forthcoming yet. It’s got to be software/file problems as it was all working at first.
37 Gary // Oct 22, 2008 at 7:46 pm
There is a BUG in the “where am I” feature.
The “nearest intersection” is NOT the nearest intersection. In testing that I have done, it is off by from one to dozens of blocks. In the worst case, it is so far off as to be useless.
Example, one test displayed a “nearest intersection” 1 mile from my location. The implication then is, if I am 1 mile from the displayed “nearest intersection, then by extention, I could also be 1 mile away in the other direction. So I could be in a 2 mile diameter of the displayed “nearest intersection.”
I don’t know what logic it is using to find the
nearest” intersection, but whatever it is, it is WRONG.
Don’t plan on using it to call emergency, a cab, or anyone who wants to know where you are.
BTW, I am running OS v4.2 which is the current release.

hi, i have been trying to send sms from my 760 via my samsung f400 on o2. the messages remain in the outbox but do not send. i can make
and receive voice calls though. any advice appreciated. cheers dave.
40 Dean // Nov 23, 2008 at 9:34 pm
Hi Dave,
My first suggestion would be to try using another phone as a test just to see if you get the same problem.
41 Ken Keet // Nov 26, 2008 at 11:03 am
Hi I have just arrived back fro Saudi Arabia and will be going back for another two year contract. I would need one with “middle east” spec. What do you suggest, please
Ken
42 Dean // Nov 26, 2008 at 12:37 pm
If you like the spec of the Nuvi 770 then you could get that one (or the cheaper Nuvi 760 which does not include North American maps).
Then you could purchase the City Navigator Middle East NT maps CD-ROM/DVD from Garmin and install them onto an SD card which you can slot into the side of the Nuvi.
Have a look at the Garmin City Navigator Middle East NT maps page. Click on the ‘View Map’ tab to check the map coverage is OK for what you need, and the ‘Products tab’ for Garmin products compatible with this map.
It is not cheap though at £179.99, especially when you consider the price of the Nuvi 760/770 on top of that. You could consider a cheaper Garmin if required.
43 Mike // Nov 30, 2008 at 10:32 pm
Fantastic review. I’ve just ordered a 760T for
£177. Hope your getting a commission from Garmin.
44 Dean // Dec 1, 2008 at 8:38 am
Hi Mike,
Glad you liked the review. If you bought the 760T via the Amazon link in this review then yes I do a get a commission fee from Amazon. It all helps go towards the running costs of the web site
45 Martin // Dec 9, 2008 at 11:33 am
Hi Mike.
Just came across your site very impressed. You might be able to help me. I just brought a nuvi 760 which I love but I’m having trouble with the blue tooth I have a motorola razr v9 which is compatable but when I get an sms message and I press the listen button I only get one word and sometimes just the word comma. I have noticed when I turn on the gps and it pairs up It does not send the in box messages across hope you can help regards Martin
46 Dean // Dec 9, 2008 at 8:44 pm
Martin,
There have been some issues reported with bluetooth before on some of these Nuvi systems, not just the 760.
One thing to try is select Tools from the main menu, then Settings and then Bluetooth. There is a Connections screen, you could try removing your razr v9 from the list and then re-add it and see if that fixes it. There is also a Troubleshoot button at the bottom of the screen, not sure what it does but worth having a look at. There is also a Restore button which I’m guessing resets the bluetooth.
As a last resort, you could try doing a factory reset if you don’t mind losing any favourite destinations, etc. you may have stored on the 760.
47 Martin // Dec 10, 2008 at 8:23 am
Thanks Mike.
I tried those things ans still nothing. The funny thing is if I compose a message on the nuvi it will play back, and once it actually played part of a messgae tried talking to garmin but no answer. Thanks for the effort
48 Martin // Dec 10, 2008 at 8:25 am
Sorry I have been calling you Mike and just realised it is Dean sorry mate
49 Edhree // Jan 25, 2009 at 11:48 am
Good review,but i have question regarding the LANE GUIDANCE feature.I thought that the 770 got this ,can you tell if this is true or not.Thanks.
50 Dean // Jan 25, 2009 at 12:59 pm
Edhree,
Glad you liked the review. The 760/770 don’t have lane guidance. If you want this feature take a look at the 765/775.
The 765/775 are basically the same as the 760/770 except they have lane guidance, photo navigation and I believe more memory. The only downside to the 765/775 is the lower battery life, 3hrs compared to the 5hrs on the 760/770.
51 Martyn james // Jan 28, 2009 at 9:43 pm
Hi
New to site, brill advice.
Bought a Garmin Nuvi 610t from auction, have receipts ect.
When i switch the unit on it asks for the unlock code, which i dont have. Have contacted Garmin they want £29 to unlock it, its not stolen or anything.
Can anyone help please
52 Dean // Jan 28, 2009 at 10:06 pm
Hi Martyn,
Sorry, I don’t know of any alternatives except trying to search on Google and see if anyone offers it cheaper.
53 Lee // Jan 29, 2009 at 3:08 pm
Does anybody know if Garmin (or a generic accessories supplier) have developed a dashboard attachment, similar to the one Sony NVU developed? I know Garmin have the heavy, large, non slip pillows to place on the dash, but I was wanting something less bulky and a neater solution. I don’t want to use the semi permanent discs either. Thanks.
54 Dean // Jan 29, 2009 at 5:36 pm
Lee,
If you don’t like the Garmin friction mount due to weight and size, then the only other thing I can think of is a mount that slots into a car air vent, but I’ve heard they can pop out if you go over a bump, so may not be any good.
I use a Garmin friction mount myself, I personally don’t think it’s too big or heavy, it nevers moves off the dash and is portable. It gets excellent reviews on Amazon too, so worth considering if you find no other alternatives.
55 David // Feb 2, 2009 at 7:00 pm
Can you please recommend a sat nav that does the following:- Reliable, gets me there with options for routes, enables “way points” to be used, traffic, Uk & Europe, lane assist. Enjoyed the 770 report but it doesn’t tick all required boxes.
56 Dean // Feb 2, 2009 at 8:20 pm
If you need the lane assist then you could consider the Garmin Nuvi 765T
It has UK and European mapping.
The 765T/775T are both basically the same as the Nuvi 760/770 but with new features like lane assist, photo navigation and 3D building view.
Amazon must be doing a deal on them at the moment as the price for the Nuvi 765T is only £242.99 which is cheaper than the older Nuvi 760.
Worth considering but still quite a lot of money to splash out on a sat nav.
57 Edrhee // Feb 2, 2009 at 9:55 pm
Just want to ask if you do reviews of TOMTOM as well and to say thank you for replying to my question.
58 Dean // Feb 2, 2009 at 10:05 pm
Edrhee,
Not yet, but I do intend to review some TomTom systems this year. I’m hoping to get some review models in the next month or so.
59 David // Feb 3, 2009 at 9:16 am
Dean, thanks for 765 recommendation but will it take way points or do I have to reprogram next step?
60 Dean // Feb 3, 2009 at 5:22 pm
It supports up to 1000 waypoints. You can create waypoints using an application called MapSource on your computer. You can then transfer these waypoints to your Nuvi.
You can also create routes, let’s say you need to drive to 10 different places in one day. You can create a route for all 10 destinations in one go and then the Nuvi will figure out the most optimum route to get to those 10 destinations.
You could also add via points. So if you want to go from A to B via C you can do that too.
You may also find the owners manual useful.
Hope this helps.

Great review Dean – thanks.
I am about to enter the ‘digital age’ & buy my first satnav. I will mostly need UK maps, but am going to US on holiday in a few weeks & was planning to hire a satnav at about £50 for the 10 days. Am now thinking of getting the 770, but have a little ‘niggle’ that I will get to the states & not be able to access maps etc (following a few of the comments on here). Do you think it’s worth the risk, and if so, can you recommend a place to purchase (preferably on that would give you a commission?) Cheers!!
65 Dean // Mar 2, 2009 at 1:02 pm
The 770 has full USA and Canada mapping so should work fine the States. I just tried an example route from New York City down to Miami and the route looked fine. Whereabouts are you going and I’ll try plotting an example route for you.
If you decide to buy then you can use the Amazon link at the bottom of the review. Any sales through that link give me a commission which helps contribute to the costs of running this web site. Thanks.
Also make sure it has the latest maps on it, if there are more up-to-date maps available you should be entitled to a free upgrade from Garmin.
66 Weaponsguru // Mar 2, 2009 at 2:24 pm
Thanks Dean, I’m just going to be driving around Florida. I’ve been there a couple of times before & never had any problem finding where I’m going, but I will have both my wife & 11 year old daughter “assisting” with the navigation this time. I thought it was worth the extra money just to save my ears from their “help”
Most routes will be “standard tourist” routes, but I am thinking more of the initial drive from Miami to somewhere west of Kissimee. The highways won’t be a problem, just wanted to be sure that I can input an address (haven’t got exact address yet) & program route before I go.
If/when I but one, I will use your Amazon link.
67 Dean // Mar 2, 2009 at 2:38 pm
I tried plotting that route on the Nuvi 770 and it looked fine. Good luck with your trip
68 Weaponsguru // Mar 2, 2009 at 8:48 pm

Cheers for the review – I’ll let you know how I get on (hopefully no “locking up” of the maps!)
69 Dean // Mar 2, 2009 at 8:59 pm
Thanks. Make sure you upgrade to the latest software version too using the Garmin WebUpdater tool.
I’m running software version 4.60. The WebUpdater will also update things like the GPS software version, bluetooth software version, etc.
70 Finn // Mar 8, 2009 at 1:06 pm
Would like to order my Garmin 770 from a UK supplier (much cheaper than from a supplier in Denmark). However, Amazon.uk and other UK websites do not seem to deliver outside UK. Do you know og any UK websites that do?
Thanks in advance for your help and thanks for the great reviews.
71 Dean // Mar 8, 2009 at 7:01 pm
Finn,
You could try looking here. They will ship to Europe.
72 Weaponsguru // Mar 17, 2009 at 12:58 pm
OK, I’ve had my satnav now for a couple of weeks. To be fair, I’ve not really had much need of it, but I’ve tried it out a couple of times, with no problems.
I upgraded the software online, as recommended – cheers Dean!
The bluetooth to my phone works great, & the voice dialing from my nokia N95 works every time – no problems like the ones you encountered.
The only thing that I am now thinking is that I wish I had had a look around to see if any of the satnavs had a function to allow the watching of films via the screen. I know that my old car (RX
had an in-built satnav that could be converted towatch DVD’s, but I never really used the thing, as I knew where I was going most of the time )(and at no better than 12 miles per gallon, I couldn’t afford to go far!!).
It would be a nice function for the 4 hour drive up the Florida interstates if I could let my daughter sit in the back & watch a film while I drove (less “are we there yet” comments!!)
73 Dean // Mar 17, 2009 at 5:37 pm
I’m not aware of any sat nav that does this.
You’d probably have to take a different approach, buy a hand-held device for watching movies (something like an internet media tablet or similar) that can also double-up as a GPS receiver. Although I’d have reservations about how good the GPS would be on such as device. I’d imagine a dedicated GPS system would perform better from a navigational viewpoint.

I had a search on Google and found a GPS Iceland page that may be of help.
I also found another couple of retailers selling Icelandic maps but not sure of compatibility with the Nuvi 760.
You could also try contacting Garmin directly if you have no luck elsewhere.
77 Innes Stephen // May 5, 2009 at 1:00 pm
Had to travel 200 miles to los Angeles International Airport through dreadful storms which caused major interstate accidents. The Garmin navigated me around the accidents and traffic problems through changing interstates and diverting through suburban neighbourhoods. Was only 20 minutes longer than normally expected. Worth ever cent I paid for it and more for that journey alone.
78 Bill Bertham // May 5, 2009 at 3:14 pm
I am having trouble on start up on my 775T It takes ages for the maps to load and the battery life is abysmal. I travel a lot in France and Spain and the pronunciation of place and street names is awful. Another annoying feature is the auto complete function on the towns and street. Sometimes when I enter a town it auto completes before I have finished, 9 out of 10 times this is OK but sometimes the place I am looking for does not come up in the auto complete list. This is very annoying and means I have to search through the maps until I find the place and do the navigate here function. There should be a way that the auto complete function can be turned off. Apart from all that I like the unit very much.

Best site info for Nuvi 770 with great rewies.
Im about to order the garmin nuvi 770 and i have to clear some inquiries.
Starting with : what languages the nuvi770 is supporting for voice guidance and internal menu languages.
And second if the IGO maps are compatible with nuvi 770.
Thanks
80 Dean // Jun 10, 2009 at 7:16 pm
Pacos,
The Nuvi 770 supports many languages. Which ones were you particularly interested in?
I don’t know about IGO maps unfortunately.
81 pacos // Jun 14, 2009 at 3:33 am
Hi Dean
The languages im interesting are the Greeks and Romanian, but always for both, voice guidance and internal menu.
Thanks again for your reply
Pacos
82 Dean // Jun 14, 2009 at 9:59 am
Hi Pacos,
Voice guidance and internal menus support both Greek and Romanian.
Voice guidance for both those languages does not support Text to Speech (TTS) though, so the Nuvi 770 cannot speak the street names. It will just say something like “Turn left in 100 metres” rather than “Turn left in 100 metres into West Street”.
83 NKT // Jul 2, 2009 at 5:06 pm
@Bill
It sounds like your almanac data is messed up. Back it up then do a factory (hard) reset, and let it find the sats (takes ages, up to 30 minutes) and it’ll re-build its database, and so should be faster from then on. The low battery will be because it is always looking for sats rather than knowing where they are.
Also, normally the Garmin only auto-completes if there is only one option left in the list that matches.
Also, your Welsh issue is probably because you are telling it to look in England first, so the Welsh postcodes aren’t in the list. I did it once and looked a right wally when the wife corrected me!
@Gary
It’s the nearest MAJOR intersection, generally.
@Erol
The Garmins all auto-zoom in and out depending on what’s happening. At junctions it is a tight zoom, while it pans back a bit on highways.

Hi.
I am unable to get a Garmin Map database for my Nüvi 760 covering Iceland on SD card, but I can get it on a CD. Does anyone know if I can transfer the CD map data base to a SD card and then use that, in order to avoid erasing the preinstalled map data base covering Europe

That should be possible. I found this link which explains how to transfer maps from CD to SD card. Hope this helps.

87 Dean // Jul 27, 2009 at 8:06 pm
Hi Shawal,
It’s possible the battery has completely drained. Try connecting the Nuvi 770 to your PC via USB and leave it connected for 3-4 hours. Then disconnect from your PC and see if you can switch on the Nuvi 770.
If that doesn’t work then you could try a hard reset. Turn off the Nuvi 770. Then hold your finger in the bottom right of the screen, keep your finger pressed against the screen and power on the Nuvi 770. Answer yes to the question when prompted. Be warned though, this might erase all personal data like favourites.

89 Dean // Jul 28, 2009 at 9:19 pm
I think what you’ve done so far is correct. For some reason your Nuvi 770 keeps switching itself off. Have you tried phoning Garmin? I’m not sure what else to suggest.

I don’t think you can download a free version of MapSource from the Garmin web site.

When I then I install a map from a Garmin CD and try to open mapsource, I get a new message saying: Incorrect language dll file.
Can anyone tell me how to solve this problem?

Can you confirm. Have you installed the full MapSource product from a CD? The MapSource download from the Garmin website is just a software update, it is not the full product. You cannot run MapSource from a software update, you need to install the full product, otherwise it will fail to start.

Hi Dean.
Thanks for your reply.
You are right about my incomplete MapSource installation.
When I tried to use another computer there was no problems.
It appears that the reason why I don’t have the full MapSource program installed already, is that when I bought my GPS, the City Navigator Europe Map was already preinstalled, and Mapsource was not a part of the accessories supplied from the dealer. The only way for me to get the entire MapSource program now, is either to buy a CD that contains both a map and the MapSource, or to buy an update to the preinstalled EuroMap on my GPS.
Best Regards,
Erik

Hi! I am looking for a satnav that can autosort a route for multiple destinations (I am a delivery driver) and this seems to be the ticket. However I cannot for the life of me find exactly how many destinations can be added to the satnav for it to calculate a route – ideally I need a capacity of around 50. Can this do the job, or is there another I should consider?
Thanks a million!

Hi Graham,
I will test this out for you this evening and let you know.

Did some more testing this evening. The Nuvi 770 should be able to handle up to a maximum of 50 destinations. I created one route with 17 destinations in my limited testing but it was able to autosort these into the most optimum route.
According to the Garmin web site the Nuvi 770 can store up to 500 waypoints. If you think you might need more then there is always the Nuvi 765 or 775, they can store up to 1000 waypoints.
