I got my TomTom Rider 4GD00 new a number of years ago and it's worked just fine until now. It has one problem. The time is pretty much stuck at 12:00. I've repeatedly tried resetting it and it might take for a very short instant, but just goes right back to 12:00. It never looses power or anything, and I've hooked to the computer and updated it a couple times but nothing helps.\nAnybody seen this happen before or know what's going on? THANKS.
