my go 720 is switching screens from the map nav screen. I set a route, or have it just turned on and it will switch to another screen - (one was asking me to locate police stations.) It also keeps asking me to choose country and language? contacted Tom tom support. Formatted go 720 and eventually managed to re load software - but the problem of screen jumping is still happening. can anybody suggest a solution. I am running xp Pro as my main computer. But the sucessful (well only to download) dowloads have been on my laptop with windows 7. Probably as there were no TT files on this comp.
