Can anyone advise me regarding loading full postcodes on my Tom Tom Go classic, (first model). I can't search a location by a full postcode, only partial. I have been onto tom tom web site who give instructions for downloading the full postcode infromation direct to the tom tom. I have tried this but the memory card wont take it, it's saying that I am nearly 10mb short and won't let me download it. What should I do, if a buy a larger memory card, this would be empty of everything, so how would I get the tom tom programme onto it including the full postcode search. Is this possible to do this or do I have to buy a new Tom Tom card with it all preloaded. Can someone please help? England UK.
