I picked up my Model S from the dealer in June. After I got it home, I wanted to take my Sirius radio account off my BMW and put it on my 2020 Model S. The car came with XM radio on it. My salesman had told me that Tesla did not have XM radio. When I picked it up, and showed him XM was on the screen, he said it was not connected to an antenna. Two days later, while fooling around with the car, I touched the XM and a preview of the radio came up loud and clear. I then called XM and got a gentleman who told me that my radio number shown on the subscription screen was not in their system and I needed to contact Tesla and get them to register the radio. Make a long story short, from the dealer to customer service Tesla does not register radios and is not in the radio business. I called the Sirius people back and made the mistake of asking for the man I had talked with before. He closed the account on my BMW, but said he still could not accept the subscription on my Tesla. I argued with him with no results.
Then I wrote the people at Sirius and laid out the problem. Got a nice e mail and a telephone call with a number and a corporate person to talk to. Registering the Tesla radio number was no problem. It WAS in their system, under another VIN, and all the guy had to do was switch it over to my VIN. I hope no one else goes though this if you have XM. They even gave me 3 months full subscription for free.
