I have a new Garmin Zumo 595. Absolutely everything works great on it excepting that it will not consistently work to make or receive phone calls. It pairs beautifully with my iPhone X to stream music, smart notifications, and all the other things, but it will not successfully make phone calls. The call goes through, but there is no audio in the Sena 20S headset. The Sena also pairs beautifully with the Zumo 595 for everything except phone calls. Anyone know a solution to this?
