I miss my satellite radio being integrated into the vehicle interface (not just on the phone via bluetooth). I did not opt for the premium audio package, but I do have the pano roof. Has anyone figured out a way to enable XM without the premium audio? The assumption here being that pretty much everything needed for XM is already prewired in the car. Or maybe not everything, but with a few small modifications? Or is it software-locked and there's nothing at all to be done about it?
