I'm looking for a wiring harness adaptor for my C5 A6, currently fitted with the Nav Plus unit but looking to fit my Pioneer AVH-270BT touch screen double din. Having removed the Nav Plus I found that I needed something that would link the Bose system. The current unit is not that great, FM comes and goes, changed the amp as well, CD player crashes and the sat nav doesn't work. May need to fit a new aerial and coax from the dash. Appreciate any pointers on where best to find such a harness as sure someone must have done a swap for something newer?
