Then what you can do is order the less expensive sm 10 and pair your phone to it and get the adapter that goes from the 5 pin din plug to a 3.5
and plug it into.
the sm 10 and also pair your head set to the sm10
This way you can answer your phone, make calls and listen to any music from phone or bike through headset.
OH, that darn Apple company ounce they got you, you are there and that's it.
Don't they make an adapter to give you a 3.5 plug.
