Since the wife and I sometimes like different music, we found that by bluetooth syncing each of our individual Sena 10's to our individual phones, we now can each listen to different music, make and answer calls from our individual phones, and still talk to each other while on the road. Only drawback is that since we are not sharing the music, the audio GPS will not broadcast to her. However, since she leads, this gives me an excellent opportunity to tell her where to go.......
