ST 2021 - how can i keep the radio OFF?

[cillik]

for some reason my radio keeps turning it self on whenever i restart the car
As well I noticed when I leave the car running and walk away the radio goes to full volume
I never listen to the radio, how can I just keep it OFF all the time?

Have you tried resetting SYNC?

Funny, sometimes the radio in mine is off on start up, and it won't turn on unless I complete a hard reboot.
