Ok I will see if I can explain this. My bike has the stock j&m intercom system built into the bike. I donr use it. Instead I use my sena SMH10. One problem my gps is a garmin 2720 and the audio only works through the j&m intercom. Is there a adapter that I can plug into the stock port (where my j&m intercom system use to plug in) that adapts it to a 3.5 headset plug? My sena has a plug for aux audio. That way I dont have to buy a new gps with bluetooth.
