Hi everyone, need a bit of help, I am just about to deploy to Afghanistan and my wife will be using my 2006 A6 Avant S Line and I wanted to update the sat nav as it is still on the original 2006 DVD. Just been to the Audi Dealership and they quoted me £200, so I told them to stick it where the sun don't shine!! Can anybody give any advice on a cheaper alternative and anything else that I need to to for the update!! All help welcome!! Thanks
