I have the old style ( I think CD based) system and would like to update it to the later style DVD nav ( I think used in the last of the old model A6's). If I could get hold of a DVD nav unit, would it fit? Does anyone know of a specialist who could help me?
You'll need someone with VAG-COM to reconfirgure it to your car, but otherwise installation is plug and play IIRC after a bit of fiddling around dismantling dash/ removing glove box etc.
