etc

I have an older B7 A4 with a Bose Symphony stereo system. I have a Dension ICE link installed and it works fairly well, but have a few things I would like to have done.

1) I read that there is now a SAT splitter, so I can recover my SAT access, which is currently disabled.
2) Controls don't seem to control the songs anymore, and there is no song information
3) The phone module has never worked (I believe the installer didn't know what they were doing) and would like it resolved

Willing to upgrade - perhaps it's just a firmware issue as well. Does anyone know a shop that knows the Audis pretty well? Especially the B7s?

Thanks in advance!
