I'm hunting for a Sirius Satellite receiver for my 2009 328xi. I bought the car as a CPO. This is the last of the cars built that require an external (trunk mounted) satellite receiver; stupid design. All builds after mine include the capability in the head unit. The dealers have these on restricted sale and want $1200-! Finding a wrecked car to strip the receiver is tough. I don't want to clutter the car with an after market receiver. My buddy owns a salvage yard and he searches periodically, but apparently the salvage business is technology challenged so he can't run an on-going auto search like I have on eBay. part # 65129192274 is what I'm seeking. Anyone know a source that specializes in used BMW/Mini electronics?
