So what is not working. Sounds like you have them all paired correctly. I use a Sena headset but have the same pairing. iPhone is paired to Nav V and the Sena is paired to the Nav V. I can answer and make calls through the Nav V. For music, I loaded my songs onto a micro card and use the Nav V. So far everything pairs up and works flawlessly.
