Hi i have a corrupt map not sure why, how do i restore the default map from unit? i have disc but i think that's just the home software where are the original maps stored?. WHen i brought the unit new it did have maps in it are they the latest or do i need to update? how often are the maps updated? i just need to get past the corrupt error message i am not sure what i did to my map sigh. how do i start a fresh?? Also if i give this unit to friend to use on trip can they sign up a new account it seems to always log in with my email account? why dont they make tomtom like a computer reformatt and start again??
