Hi everyone, I just bought a 05 X5 4.4 with Nav, but the "telephone" option won't show up on the display. I checked and it does have the bluetooth module in the back as well as the paperwork with the passkey, etc. so I know the previous owner was using it.

Is there a special way to initiate the module. I tried unplugging it and plugging it back in as well as disconnecting the car battery, but still nothing. Any thoughts?
