Just got a zumo 390 and have Sena 20s and Sena SM 10
Wondering if I have this right.As of now my phone is paired to the Sena sm10.
I have the headset plug adapter plugged into the sm10, this puts all music into my headset,Sena 20s.
Now is there a plug on the zumo that I can plug into the SM 10 to allow me to hear directions?
