XM satellite to car is compressed and boomy-- almost unlistenable.As with so many things in audio: It depends. XM in my car does indeed sound poor, with that compressed, swishy sound that XM is known for. But the XM radio in my wife's car is much, much better. It's still not as hi-fi as a fine FM station (not that there are many of them around these days), but it's listenable for the car, imo.
