I have the wired cb/radio/I pod setup on my 2010 Vision. Yesterday while on a ride my wife could no longer hear me when I spoke.  (No she was not  just ignoring me ). I can hear her and the music. She can hear the music but not my voice. When I speak the music stops in my speakers and in my wife'said but she can not hear me. I have switched headsets, mine in back, hers in front and the problem persists. I am thinking the jack is the issue. Does anyone know how to test the Jacks? I am not sure if it's the front jack or the back.
