I'm using a Pioneer 7900 Bluetooth radio and I can make outgoing calls thru bluetooth with my iPhone, but I cannot receive calls thru bluetooth on the Pioneer with my iPhone for some reason.
I still get the call, but it only goes to my iPhone and does not go through the speakers like it should with the pioneer bluetooth.
Also, in case this applies to anyone else, I had problems having my pioneer recognize my iPhone after pairing at first, but then I read the manual and the issue was that I had to register the iPhone with the radio. It was just another part of the setup process; after that, the pioneer 7900 always recognized my iPhone successfully.
