I think I've tried everything with my tomtom and i'm at whit's end with this dang thing.. i tried installing the map update the other day and my computer froze in the middle of it. I wasn't aware of the fact that i was supposed to backup my tomtom before installing updates onto it, so no i cannot restore it to the point that it was at before.. i have tried just copying the system files, i've tried formatting my tomtom and starting from scratch.. when i try to reinstall everything, i consistantly get an error that says it failed to copy a file, and the file is different every time. I want to be able to install the tomtom application files and the map manually because tomtom home keeps messing up my tomtom. when i try to turn on my tomtom, it just stays at the load screen and never turns all the way on.. ive tried formatting it to fat and fat32. i think i've tried everything that i could possibly try. is there anyone that could upload their tomtom xl 330s system files so that i could just copy them exactly and have that work? please help
