I have an 2004 Audi A3 with the single DIN concert II HU and BOSE. I am looking to fit a bluetooth kit.
I am planning on using the 10pin ISO connector to connect to the Mute and Telephone +/- inputs. I have read on a number of forums that the mute pin will silence what ever is playing on the radio and route the audio from the telephone +/- connections through the front speakers.
Will this work with my BOSE system? i.e. will the HU route the telephone audio to the 8 pin non-power ISO? In my case all the speakers are routed though the BOSE amplifier, confirmed by the only audio out being a single line out to the amplifier.
Do I need to program anything to let the HU know about the phone connection, i.e VCDS?
Any advice appreciated. Please feel free to move this if it would be more suited to another section of the forum.
