Recently, a B7 Concert II+ come up on eBay at the right price so I have bought and installed it in my 2003 B6 A4. Everything works fine (with kufatec loom) with the Concert II+, but my steering wheel controls aren't really working. Volume control works as it always did, but the up/down and left/right controls (freq up/down and next/prev preset channels) don't work at all. I've looked at the coding options in 56-Radio and changed the code just to see if it has any effect, but it doesn't.
Obviously, I'm aware the radio was designed for a B7 and it's in a B6. I just wondered if anybody had any thoughts as to whether this can be made to work?
