Wanted to share this about SXM. When I bought my Tesla, I was told at the Tesla 800 number and the Palo Alto Rep at Stanford that new Model X’s, 2019, did not come with SXM. Instead, to get SXM, you need to use a phone with Bluetooth and the SXM app(an acceptable solution). About 3 days after owning my 2019 Model X long range, I noticed that it had SXM so I activated it and it works great. I ordered from existing inventory and picked up the vehicle at the Fremont distribution center. When I was previously going to do a custom build online, I did not notice a feature for SXM. I am, therefore, unsure, for new Tesla owners, if and how to order SXM. if you have insight and would like to share, please do so here.
