I just bout a pair of sena 10s so I can talk with my wife riding. I have a 2007 wing and she a Can Am Spyder STS. But I want to hear my GPS so I bought the Sena Freewire. Bought them all from Rocket Moto. My question is there a torn off switch on the freewire if I want to ride with my older helmet wich is hard wired. In case I ride with people who do not have bluetooth set ups?
