My Nissan has a center console that cedes ALL controls to the rear camera app when the car is put in reverse. So if you have music playing you can twist the physical volume knob all you like while in reverse and nothing will happen!

If you parallel park daily you'll probably experience this every time: You jump in the car, start it and put it in reverse. The music will start playing after a couple of seconds at the level that you had during your noisy commute. You now have the choice to put your car in neutral, change the volume and then go back to reverse and exit your parking spot OR try to navigate out of your parking spot with music blasting.

I believe Ford automatically lowers the volume to barely hearable while in reverse — since otherwise I think passing over the UI to a more important component is a good decision.

Does the power button work, or is it also locked out?

[RubberbandSoul]

I just checked. The power button is locked out but the volume knob works now.

Now I feel stupid, but it's quite possible that it has been patched during a yearly service.

Maybe it's a reasonable design decision. How often is the car going in reverse? Should you really be fiddling with the UI when the car is in reverse? Sure there could be a passenger, but is it such an inconvenience?

No, I agree that it's awful. I rarely want the volume when I get in and start the car to be the same as it was when I ended my last trip. And not "fiddling with the UI" is exactly why there should be a mechanical potentiometer knob that is always available by feel to let me quickly spin down the volume and get back to driving without being distracted or annoyed by the radio. The need for that in Reverse isn't any different than in Drive.
