My TomTom One has just recently decided not to work anymore. I was going on the road yesterday so I did an update to get the latest GPS fix. I then jumped in the car and took off. Then I noticed my TomTom was not getting a GPS lock at all. I've reset the factory settings, didn't help. I restored an old backup...still no good. Then I noticed that when I was operating the TomTom through the TomTom Home software, it was finding GPS' like crazy. So then I turned it off, unplugged it, turned it back on...and when unplugged from my PC, still no GPS. HELP!?!?!
