XM satellite radio now requires panoramic roof - for once I'm glad I bought early!!!

Xm is radio quality at best. At lease in my lexus version I jave. It ain't cd quality. Slacker recently offer 320kbs, at min I think u can do 128kbs, which is cd quality

Sirius Satellite Radio still sounds awful after all these years - CNET

Slacker's new 320 kbps option is not supported by the Model S app, not as far as anyone can tell. There is a thread about it elsewhere.

XM sounds about as good as AM radio, in my opinion. No comparison to Slacker or TuneIn - those are much, much better quality.
