Right, I have 2 Audi A3's they are exact same shape one's a 58 plate and the other is a 09 plate. 58Plate has a Concert Stereo, Bose Sound, iPod Doc... so I'm looking to put the Navigation Plus in it as i'm selling the 09 and the 09 doesnt have Bose Sound but has iPod Doc. I took them both out and the Navigation Plus seems to have more connectors than the Concert Stereo and they both won't switch straight over does anybody know what I have to do. Do I need any sort of adaptor? I do realised I need to purchase a Antenna.. Any help would be appreciated as I don't want to take it to a shop nearby as they just rip everybody off I paid Â£90 previously he said it needed all rewiring but all he did was put a adaptor on.
