Help, Driving home and my radio went silent and the display says "PHONE " no functions work on the set nor on the steering wheel but I havent got any phone system fitted. Is the radio now scrap? Its a genuine Citroen unit. I have disconnected the power supply to see if it resets but to no avail.

The telephone mute circuit has developed a fault. This is a simple repair but can only be done by a professional.
