Go look at the bluetooth box and tell us what hole the p-bus cable is in

 

I'm having a similar issue. I installed the AVIC N4 and the BTB200. The P-bus cable is plugged into the "BALCK" hole in the bluetooth adapter, which is the furthest one from the power source. Then I have this plugged into the BLUE hole in the hide-away unit. No problems pairing the phones. When I make a call I cannot hear the other person but they have no trouble hearing me. Any suggestions?

 

I'm wondering perhaps the bluetooth unit is defective? Just on the off chance I messed up or the wiring was messed up I unplugged it from the "black" hole in the bluetooth unit and plugged it into the "blue" hole. Still had the same problem, no difference whatsoever. So I moved it back to the black hole and then tried re-seeding the hide away unit. Still no luck.

 

Also the nav is working fine. And the radio works great. Any suggestions would be appreciated. Thanks

Ok so finally talked to a crutchfield dude that knew what he was doing.

 

I have a 2002 bmw 330xi. They had provided me with an adapter for the wires. In the back of the Avic n4 there are 2 plugs that have wires coming out of it. One is a blue plug the other is a white plug. I had taken the blue wire from the blue plug and attached that to the blue wire from the adapter. There is a blue white wire from the white plug. Apparently what I needed to do was hook the blue and white plug to the blue wire on the adapter not the blue wire from the blue plug. The blue white wire controls the amp apparently which is why I wasn't getting any sound from my bluetooth. So anyways long story short everything works now.
