Today when I backed out of the garage and started driving the XM radio volume was low. So I turned the volume knob but the volume wasn't changing. I noticed that the touch screen was showing "Audio Cue Volume" whenever I turned the knob. I tried turning the infotainment off and on but it stayed stuck in the audio cue volume mode. I finally went in the config menu and entered the screen where you can set the audio cue volume. When I came out of that screen the volume knob returned to its normal function.
Anybody else experience this? I have no idea how I got stuck into this mode.
