So what I want to do in my 2000 A4 B5 is use the CD changer input to link in a bluetooth transceiver so that I can use phones, ipads etc to play music. I have been looking but cant find the pin connections for the 8 pin connector. I would be grateful if you would be willing to share them. I have seen the connector kits on ebay that cost about £65 but I am ok with a soldering iron and would be interested to make it work myself if possible.
