last monday i updated my tomtomxxl550m. tuesday i drove 15 hours away. last night i updated my tomtom just so i would have the newer updates. today i try to use my tomtom and it won't go past the "this device belongs to screen". i have an older backup (way tooo old) so i tried restoring and that seemed to work, except it insisted on doing an update immediately. and went back to the loop of "this device belongs to". i tried the official site which has a listing for "my device is stuck in a loop after updating" which has you copy a file to your computer and then delete it from the tomtom, but it is still stuck. i need to drive back home soon. any suggestions please!!!! THANKYOU!!!!
