This is a discussion on New to TomTom within the TomTom ONE forums, part of the TomTom category; Will my TomTom One charge up while it is connected to my PC by USB Cable?...
If its silver its one of the V2 onwards. If it has a memory card slot its a V2. if it doesnt have a card slot its V3 or V4. The main difference between V3 and V4 is the software and map version.
These should all charge via USB.
