Just picked up the 2007 A4 with the base stereo. Having a devil of a time finding the proper Sirius Tuner part number for this car. We have called the dealership parts department and he doesn't seem to have much either.

Have found the 8E0 057 593 but I think it only specifies for 2005 or 2006 models.

FYI the car does NOT have Nav and does NOT have tire pressure monitoring system.

Any help is appreciated. Bit worried about the 2005 or 06 tuner being the same, since I think the radio has changed for 2007. At least it looks totally different.

Thanks!
