Anyone know how to get the steering wheel audio control interface working on a 2006 S4 B7 with this Sony head unit. Brand new top of the line unit & been into audio workshop three times and still won't work. Ideas ???

 

Yeah, that one's easy.

Metra has a new universal steering wheel control remote that works very well, and it only requires you to splice 2 wires. A very very easy install.

It's the Metra Axxess ASWC, and here's a link to it on Amazon:

Enjoy.
