We had the c. b. installed yesterday ,no headsets yet, I am getting the J&M lower cord for our Elite 584 headsets, but while trying to check reception talking from my Venture the dash shows the RX recieving but cannot find out how to turn cb sounds on. When you push the talk button it does key static to my Venture so can only assume it is transmitting, Will cb only work through headset speakers ? My dealer is 2 1/2 hrs. away but didnt know anymore than me, settings in prefferences appears right, help!! I think I should be able to hear it recieving !
