I have a Pioneer 6400BT car stereo which is paired with my DNA. I am able to stream and listen to music through my car stereo bluetooth with Pandora, Google Music, Youtube, etc. I also am able to answer phone calls through the stereo system via bluetooth. However, I am unable to be heard when making outgoing calls. I can hear the other person saying "hello," but they can't hear me. This happens whether I dial through the phone or the car stereo headset. Is there a button that I need to check or uncheck on the DNA to make the connection for outgoing calls work properly? Thanks!
