Nene,
You have peaked my interest for sure.
So XM can work with it......different module though..
What about the FM and AM band, are they correct? European units use a different frequency band.
Is this unit the same one that would be in a 2006 A4????? I looked at an S4 wagon which had it.
Can you have XM AND IPOD interface?
I assume you have to access that elusive GALA wire in the Instrument panel....
What about the Bose Amps? etc...
