I just wonder if someone can give us an helping hand,
My mates just about finished installing a aftermarket satnav in his 2007 a4 170bhp tdi, we have got as far as fitting everything correctly, no wires unconnected........ the only problem is everything works fine apart from the steering wheel controls which are not working.
I was hoping someone may know the values for that feature when using vcds, and on what controller, i have the full version, so was hoping to check that parameter hasn't been changed by inserting this new unit.
I have checked ross wikki's site, but get more confused when researching.
Anyway if you can help... Many thanks.
