2010 Ultra Limited - Installed a Garmin Zumo 660 System. Paired my Blackberry to the Zumo. I can hear callers through my Harley Premium Headset, but the microphone does not work (they can't hear me).
Any suggestions?

Since I posted this question, here is the answer I found. I have checked everywhere and have found only one solution. J & M Electronics https://www.jmcorp.com/ offers a connection device that will enable your Zumo 660 to use your cell phone. The cost is $379.00!!! I don't want to talk that bad.

Thanks for the update!
