SiriusXM would not working if you don't pay for it.
I'm PC, and I recently rented a car at LAX, Nissan Altima, with SiriusXM. It was fine for 10 days but suddenly stopped. It said I don't have a subscription. When I returned my car, I asked the agent. He said it's new policy after covid. If I don't pay for SiriusXM, it will not work automatically. I assume it takes some time to be stopped, but it was kind of shock since I've never experienced this before.
