The speakers on the bike work fine, one of the headsets is brand new too and the cable as well. But do you know if the telecommunication system on the bike has a seperate fuse or relay? Thankslstinthot said:any maintenance done lately? I pulled a wire under the stingray one time when putting it back together. Do the bike speakers work? If not I would check the fuses.
Also check the connector in the middle of the wire from the helmet to the bike. Mine came loose although it looked like it was connected. Pull apart look at connector to make sure the connections are clean and put back together.
