Just a note if you are buying second hand Tom Tom's.
I had problems with camera updates after buying a second hand Tom Tom. Un be known to me the previous owner had "locked" the Tom Tom to his email addy.Tom Tom will only allow 2 changes with any Tom Tom unit.For example changing Pc's to accept downloads.If 2 changes have taken place you will not be able to make any further changes for a minimum of 6 months so you will not be able to access any downloads.This is to prevent copying issues on Tom Tom's part.
