Got new TT1 LE yesterday and was very pleased but after loading my home location and two favorite destinations all looked well on the demos I ran and then it locked up on me. Screen went white with a narrow vertical red line in the center. I had it connected to my computer for about an hour and the green light showed charging, while I was using it to examine features. When it went blank and the vertical red line was on the screen it was not hooked to my laptop. I could not shut it off or get it to respond in any way. left it as was last night and this morning it was off. Got in my car with it and hooked it to lighter socket and turned it on and it has worked fine for me going to church and back home today? Any ideas why it hung up and have you experienced the vertical red line on white screen!! Could it have been the battery ran down or needed charging?? Thanks for comments....
