A4 8K SALOON HARMON PHONE
Bought a harmon (original Audi) phone and bluetooth with wiring harness cos I was getting the "telephone not installed" on the screen. Fitted the wiring and put the b/tooth module behind glovebox. Had it at a few VW Audi specialists and Sandra kindly at the drop of a hat organised a late meeting with Eddie who worked tirelessly to code this. Problem is it works with the phone speakers work it mutes music I can talk and be heard and the call comes through the speakers but it doesn't display on the screen??? Any ideas welcome. Had it in at Audi Ayr and no joy. Any VCDS gurus out there can help I'd be delighted to hear. The wiring is as follows. Switched+/earth. Can high to pin 9 and low to pin 10 the rest is plug n play.
