Nor does the CD button and SAT button function. Steering wheel volume does not work as well. This was a replacement unit with same model number as before 4B0 035 195N. Then when I plug back in my old one, the volume and SAT button don't work either. I'm not sure what's going on. But my old unit which I know was BOSE still says BOSE when it powers up, the replacement does not. Any ideas?

if you have vag com see what the coding of the old one is versus the new.

And also check for codes.
