My radio mysteriously wont turn on. It reads “audio power off” and does not respond to any push button commands. The volume control ****/power **** does nothing. I’ve disconnected the battery (strangely did not ask for reset codes) and changed the fuse (even though it wasn’t bad). I have no idea what happened. My teenager started the car with the valet key, so I thought that was the problem but I’ve since started it with the standard key. And still nothing

 

There are several fuses involve with the radio system, such as under-hood Fuse No. A22 (10A), under-dash Fuse No. B37 (7.5A), and Fuse No. B5 (7.5A) (depending on model trim).

Have you tried this? Turn the ignition to ON, then press and hold the audio unit power button for at least 2 seconds.
