I just installed my Pioneer AVIC d3 and the bluetooth box with the microphone. The phone and the AVIC connect perfectly, but if I make a call or recieve one, I cant hear the person through the speakers in the car. The person can hear me but I can't. The speakers and microphone work fine because I tryed the radio and CD and it all works. I tryed googling my problem, and it seems that many people have ran into this problem, but I can't find out how to fix it.

Hope you can help me out. Thanks!

You plugged the p-bus cable into the wrong hole on the bluetooth box. There are only two, put it in the other one

Weird the head of the cable were blue, and the insert in the bluetooth box were also blue, I thought they matched then? maybe I'm wrong? I plugged the cable in the middle, next to the power supply. So I should use the insert in the right side instead?

It only fits in two. Take it out of the one its in and stick it in the other one
