I agree the Sena Bluetooth setup is trick. I have it & works like Magic to my android cell phone, plus it has a 3.5mm jack (this is a standard stero earbuds input). With this input you can get from Sena for $24.95 a cord that will plug into the F6b's 5 pin din. With this setup you can Bluetooth either phone calls or music from you cell phone, plus listen to music from your bikes stero and usb input etc. When a phone call comes in it will automatically mute your music and all you do to answer the phone call is say "hello" hands free. In addition this Sena when paired up with another Sena will give you communications with another rider up to a mile or your wife riding behind you.
