Hi!
I bought a used RR P38 and had the same problem; the radio was stuck on "mute".
At first I couldn't find a button to un-mute the system, but then I accidentally found it on the steering-wheel. All text is worn out on my steering-wheel audiocontrols, but if you press the middle butten on your left hand side and hold it for a few seconds, you will get your radio back to normal mode.
Regards,
Martin
