2015 Denali Radio will not stay OFF!

Has anyone else had a problem with turning off the radio and having it stay off when you restart vehicle?
I turn radio off but after restarting have to turn it off again.
Thanks

Yes, I have the same issue. I thought my husband was leaving the radio on but it turns out that it just doesn’t stay off.

Press AND HOLD the power button. When you press, you just mute the speakers.

Of course, all other infotainment will be off as well.

I am aware of the mute function and the "long" press to turn off the entire entertainment system. However, once you have turned it off, the next time you start the vehicle the radio is once again on!
