Hi chaps, I've just fitted a replacement automatic aerial on my A8 with the one from VAGParts as recommended in several other previous threads. It had 3x wires not including the coax cable for the radio reception itself:- Red (12v?), Blue (signal for extend/retract?), Black (ground?) I've connected it up and get proper extend/retract movement but quite poor reception to my OEM Delta-Gala Head Unit!? Anyone have any theories why this might be the case please? I also noticed that the original aerial assembly connected to a brow wire from the loom - anyone know what that wire was for? Would it have held the aerial down if the CD changer was being listened to instead of the radio perhaps? /ubbthreads/images/graemlins/confused.gif Many thanks in advance for any help that people can be with this? Cheers, BigJ.
