After pairing my new DInc2 to my Prius successfully some calls were fine but some, right in the middle of the call, would suddenly not come through the car audio system, as if Bluetooth had temporarily disconnected. Once the call was over everything was fine and I could make or take calls hands-free without doing any reconnecting or anything. This does not happen on all calls, but sometimes I hear two beeps and then a couple seconds later the sound is only coming through the phone , not the car. Cold my NAV or a text message be causing interference? This never happened with my original DInc. Any help would REALLY be appreciated, as I am in the car all day and must have hands-free.
