Connecting a Tom Tom GPS to a computer [closed]

AFAIK, when you connect a Tom Tom to a computer, that is when you can do maintenance operations to it, such as updating maps, changing voices, transfering files, etc. Because of that, it can't be used as a GPS. If you want to use it while it's charging, you should be using the power adaper that plugs into the 12v outlet (cigarette lighter)
