This article reviews the Sony NV-U73 sat nav system.
Functionally this device is very similar to the NV-U53 which has already been reviewed. Rather than repeat what has already been published, this review will just cover the differences between the two systems. I recommend you read the NV-U53 review first and then come back here to compare both systems.
In a nutshell the U73 offers the following advantages over the U53:
- European mapping
- TMC
- More memory
