I'm a recently purchased (May '13) a '12 RT - Ltd and had the Sena SM10 blue tooth dongle installed. I also purchased the Scala Q1. I am able to synch them fine and they work fine, but when I synch my cell phone (Iphone 4s) I am unable to switch to the Sena. Does anyone have experience with these two systems and able to offer advice/suggestions on this? thanks...Tim
