Hi, I bought a refurb TomTom One V2 on July 2009. It's been working great until 2 days ago. When I connected the device to the usual lap top (Windows XP, TomTom Home 2.7), there was a sub-window popped up to ask for permission for data collection for improvement. I chose YES. It crashed the lap top. Restarted the lap top. Chose NO. Crashed it again. Unplugged it from the lap top and tried to use it. It would freeze and restart itself. Called the tech support. Received an early version of TomTom home 2.6. No improvement. I was instructed to reformat the TomTom but I got a message that Windows cannot complete the reformat process. That was the end of the tech support. Since I bought a refurb unit and it had expired the warranty period by 10 days, now I own a piece of expensive plastic. Has anyone had the same issue with reformatting? Any inputs or comments are appreciated. Thanks
