When i bought my allroad the Nav DVD was missing. So the dealer gave me a disc from a 2007 A4 RNS-E. I have noticed that the compass/road name is not displayed in the DIS like on other C5 and also the unit hisses a lot when i get in the car and turn off the ignition.
Is it possible that the 2007 A4 disc has altered some sort of coding and the unit isn't shutting down and not coded properly for the car and this is what's draining the battery?
