I recommend the J&M JMCB2003 audio setup. It combines a CB radio and separate audio controller in one small box. The audio section has its own separate volume control, and the audio is muted whenever the CB transmit switch is pressed or a transmission comes in over the CB. The auxiliary audio lead merely plugs into your music source.Kawasaki used to have a full kit premium audio add-on for the Nomad 1600's. Does anyone know if they made something similar for the 1700's? I'm trying to get audio and CB in one easy control.
