I'm trying to understand what the X930BT should be able to do over a Bluetooth audio connection. When I connect my iPhone, I'm able to listen to the music/podcasts, but all of the control is through the iPhone. Should I be able to browse the music selection on my phone from the Pioneer, or is that not part of the Bluetooth specification?

i do not believe that is part of the bluetooth application on the device. You have to use your phone for controls.
