Upgrading concert HU on A6
Hi all, soooo glad I found this forum, found loads of cool info, and thats even before I've asked for help on my prob!
The concert HU on my A6 (yeah I can hear the groans) needed replacing, so I went and got a fancy Alpine unit. thing is I also have a nokia hands free kit wired into the car speakers and would like to keep the functionality.
Has anybody got any info on the colour codes for the wires found behind the standard HU. Am fairly competant with my hands and would love to be ablw to accomplish the job myself.
Any help is greatly welcomed and appreciated.
