To my knowledge, no one on this forum has ever got the complete accurate story about the lack of SiriusXM on the Air. One SA I talked to said the car couldn't have Sirius XM due to the glass roof. Yet, there seem to be add-on aftermarket Sirius antennas that should work if installed. I'm assuming the Air has a GPS satellite antenna in the roof, at least for navigation purposes, so why not one for SiriusXM? If true, Lucid deciding to have a SiriusXM app on the dash where the data is coming from cellular, rather than satellite, just seems deliberately obtuse. Clearly there's something going on with SiriusXM in the Air that we're just not getting the full story on.
