XM Satellite tuner, p/n 8E0 035 593 A, came out of my 2007 A4. I added the unit after the purchase and when the lease was up I pulled it out. Works perfectly -- plug and play. I purchased the unit from the dealership and installed it myself. I have the factory installation instructions as well . The unit fits a variety of other Audi A4/S4s, too (at the very least the installation manual says 2004 and up but I cannot tell you which ones, specifically -- that information, however, is readily available). Check fitment!

I just want to get rid of it. I would be happy to send pics. $100.00 plus shipping. PayPal is preferred. I have 100% positive Ebay feedback!

Thanks.
