As of the time I ordered my 2016 Model S, XM was only available on the upgraded audio system. The glass vs solid roof was also required as this allowed for the XM antenna.

Last Summer, I rented a ‘16 Model X on Turo without the upgraded audio system. The XM button was not present on this vehicle.

Perhaps the brand new cars have enabled this functionality.
