I have a perfect XM receiver for sale. I just took it out of my 2007 A4 2.0T because the lease is up (leased car never came fitted with one so I bought one from the dealer). I see they sell on eBay for $125 instant buy. Am asking $75 so it can find its way to a good home (car) soon. Part number is 8E0 035 593 A. Takes 10 minutes to install in the pre-wired compartment in the trunk. Thanks.
