I was driving the other day and the radio was working fine and then later on, it finally dawned on me no music was playing so I turned up the volume and there was none. The radio is working fine, you can see the station that is playing, name of the song, etc. but there is no sound whatsoever. I went to an imports mechanic shop and asked and the guy said it wouldn't be a fuse and then asked me if I had automatic volume control, sadly i didn't know but he told me how to check so I did and sure enough I have it. He said there may be a problem with that. I looked through the owner's manual, etc. and turned it off but the radio still doesn't work. Any suggestions?
