Thanks, how about the rear audio/radio controls ? They seem inactive except the Power button.
On my 2001, I have the rear audio controls. They haven't worked ever since l swapped out the stock head unit years ago. If i remember correctly, the rear audio controls only controlled the headphone jack on the audio panel. When activated, the rear speakers are muted/disabled, and the selected audio source is played through the headphone jack. Not sure if they ALL work like that or not. But my truck came with the mid grade stereo system. Its the amplified system with a factory rear subwoofer, but its NOT the BOSE system. However, when AM/FM was selected, it DID override the dash radio. I suspect its because the radio actually had to be on to supply radio audio to the rear headphone jacks. When Cd/Cassette/Auxiliary was selected, the in dash head unit stayed on whatever it was already playing, and was unaffected. For instance, if I had the radio playing an FM station and a rear passenger selected CD, the CD would play ONLY through the rear headphone jacks, and the FM radio would continue playing up front. (On the two front door speakers only). But if I was listening to a CD, and the rear passenger selected FM radio, then my in dash radio would switch over to radio. The kids used to piss me off with that all the time.
