dd on mine-older 13 - if hold the volume down button 4+seconds it does mute(does not label it, just gets quiet(red light conversation feature ). However definitely check few audio settings: equalizer, headset connection -on /off, cycle all the inputs- weather,am,fm, aux, cb. Being an 18, hopefully not another BRP connect issue(or left grip control). Is maybe possible the connection at stereo is loose, otherwise you would lest her static, sorry don’t know location. Mine was sitting on bike right rear (brake side by antenna)
