Just want to document that this also happened to us today for the first time. It's a 2013 C-Max Energi 1) Car runs fine. 2) Touching the audio on/off button next to the volume knob with the car off activates the screen in what looks like accessory mode. 3) Touching the SOUND button takes it to the screen where you tailor bass/treble etc. 4) Pressing the car start button turns the car on, but the screen doesn't respond to any audio related functions (except item 3 above). 5) That audio on/off button next to the volume knob with the car ON has no effect. 6) Phones will connect via bluetooth and make calls, but no sound is heard. We will try pulling the fuses 67/69 and 79 and edit this note or post again. -Ron
