I installed a Harley branded Zumo 660, NIM, and HDBOMM on my 2012 Ultra Classic. When testing the phone the reception was weak and I was told the person I called couldn't hear my clearly. Anyone have any ideas if there is a fix for this? Maybe I did something wrong. Or is this just the best I can expect?

Thanks

 

I have the Garmin Zumo 665 bluetoothed to my iPhone, Hdbomm, and the wife tells me it sounds great - just like a land line when I call her. No trouble at all.
