Just bought new helmets and new J&M headsets and can't seem to get either headset to work. It has to be something i'm doing or not doing cause I can't belive they both don't work. The headsets are model HS-8154 and they came with the 5-pin cord. Plugged into the connector on the bike and turning the radio on and then pushing the radio button again displays the headphones icon the sound should be in the helmet right? I get no sound in the helmet with any option, radio, CD, CB, or intercom. What am I missing?? Does the bike have to be running cause i'm trying this with the key in the ACC position.
