small black box with the magenta connector is the bluetooth antenna

I have a problem with the bluetooth module, some kind of corrupt firmware issue that won't allow my iphone to show connected on the nav screen. The phone connects fine and bluetooth streaming works, but i can't access contacts or last number dialed, etc. from the nav screen.
