Using a Treo 750 running the unbranded version of WM6. TomTom Navigator 6 is installed and working perfectly. TomTom Home was installed from the CD onto my Vista laptop and that was working perfectly, too. Tonight, I connected TomTom Home to download the map of Italy for an upcoming trip. Upon connecting, TomTom Home prompted that a new version of Home was available. So I installed it. The new version of Home says it is unable to detect a TomTom device connected. Same device, same cable, same USB port. Has anyone else had this happen? How did you fix it? Sorry, not really a Treo question as much as a TomTom question but not sure where else to turn.
