I just bought a 2004 A4 Avant.

I bought an OEM XM receiver on EBAY - waiting for it to arrive.

Trying to figure out where it mounts in the avant. The seller faxed me install instructions for the sedan - but things don't look the same in the wagon.

Behind the left rear storage compartment is a plastic housing. I removed the plastic plate on the bottom half expecting to find the XM receiver harnesses - but nothing is there.

Anyone know how to do this?

Many thanks in advance.
