no ,i think i have a new paper weight .
if you can get onto recovery . providing you made full back up. you should be able to restore using nav4free .
i cannot get into recovery or anything.
if you don't have image backup .its worth trying a backup of another tomtom.it will not get tomtom working. but might get it to a state where tomtom drive will correct problem
nothing to lose . i may be wrong ,in which case other posters will correct me.
good luck
