The main reason I got the pano roof was for the satellite radio, the other was the extra inch of headroom it provides. I don't stream music in the car as I often find cellular reception (originally HSPA, now LTE) worse than satellite. I also find the use of the cellular network for streaming broadcast media an incredible waste of resources. XM audio quality is acceptable, better than Sirius. I find it peculiar that Tesla cannot find a place to integrate an S-band antenna under the windshield, glass roof, or tailgate window, it appears to be a marketing decision.
