Radio defaults to SiriusXM

[Mac33]

Hi everyone, relatively new 2022 Sierra 1500 Elevation owner. I have noticed that when I turn the truck off and the radio is on FM and then come back about 30 minutes later my radio is on SiriusXM. I do not pay for SiriusXM because I never really used the trial so it's just the advertisement looping. Another thing to note is my auto start/stop stopped working around 1,500 miles. The dealer is currently contacting GM for the start/stop issue because they can't figure it out.

 

Is this switching from FM to SiriusXM by design or a setting? Can I disable it or is there a larger electrical problem?

 

Thanks!

The radio may still be in "demo" mode. There's numerous threads on here about issues with the sound settings resetting after shutting the truck off. I had the same issue. In the radio menu there is a factory reset or reset to defaults (can't remember which wording it is) that should fix this issue.
