Background - I've installed the Entertainment Harness, CB Comm System, XM Radio and BRP headsets. Digital console recognizes the CB and the XM radio. But...no matter how I fiddle with settings, I have no audio in my headsets - no CB, no radio, no iPod (connected in rear cargo), nothing. I have tried the CB squelch at both extremes - nothing. I have turned the external speakers ON and OFF - nothing. I have tried all the headset settings - nothing. I have tried hooking the headsets on both the driver and passenger connections - nothing.

Can someone explain the various settings than come into play when using the headsets? And can someone suggest where I might diagnose the problem? Otherwise, I'll need to drop off at the dealer and have them diagnose it.
