My car is a August 2009 with 510/sat nav but only 5 places post code, I understand that later cars have 7 place post code ?
Does the dealer load up a generic disc onto the cars hard drive when new ? having the one disc for all cars they sell ?
If I go into my local VW dealer and 'smooze' them, or pay a small sum from my son's inheritance

would they be able to load up my car with the latest CD ?
