I found an old thread about this, but in their case there was already a SiriusXM button there. Mine just got delivered today and I've never owned a Tesla before, so I'm still learning my way around the UI. On the Music tab, all I see is Radio, Phone, Streaming, and TuneIn. There's no SiriusXM button. I've tried restarting the car. Can anyone advise me on how to check if it's enabled on my software package and/or how to install it?
