I can live without the nav for now until they send me the A4 card.
Unfortunately no one is going to send you a nav card. This is on a TSB and you have to get the dealer to do it, and even then you have to convince them there is a reason you need it. They could say your system is fine and you don't need it. A dealer-install is the only way you are going to get the nav card (unless you feel like buying it yourself, then you could self-install).
