This was a real pain for me as well until I stumbled onto setting the radio to XM Radio's station #0. Fortunately XM's station 0 is empty so now it defaults to silence. Try it!the radio on ny 2020 Ascent always comes back on when the car is started. WhenI turn it off, I want it off till I turn it back on. Help!
Folks want the screen on but the audio off...Guys, hold the power button until it turns off. It will stay off when you turn off/on the car.
