Have had my C36 for over a year with minimal problems. I take real good care of everything so small problems bother me. Currently the radio head unit works the phone projects threw the speakers, I have never had a problem with the audio. Strt my car radio is on, but there is no volume??? I checked fuses and wiring nothing looking abnormal... Could the volume button be faulty or the amp just went out over night? Antenna works fine. I was reading that the AMP could be wet due to rain?? Let it dry out for a few days??
