Does he have Mic-Mutes? If so they may be muting the intercom.My buddy has taken his bike out for the first time this year... Now he noticed that his intercom is not working. Everything comes thru the headset , Nav, radio, Cb, but he can not here his passenger,nor can the passenger hear him. He tried changing helmets around without any luck,checked all the plugs... things look normal and tight. I am going over there tomorrow night to take a look and was just wondering if anyone may have any sugestions. mute buttons are off and vox is set in the medium position. Any help as were to start looking would be appreciated! 2002 Gl1800
Also check the intercom volume. It is adjusted separately from the other audio volumes.
Something obvious, but easily overlooked -- is the intercom turned on?
