Yup I can confirm pins 36 and 17 as being the power to the MULF. If you guys read the OP's post, you'll see we didn't bother with the USB hub. Its a straight connect from the USB/AUX socket to the MULF and the MULF was connected to the bluetooth antennae and microphone. I really didn't mess with the bluetooth wiring, I just confirmed that they were all there. Again, this is because my car has SA 640, so I am hoping that the car was correctly wired for bluetooth from the factory. The only wiring I did was the FAKRA cable from the MULF to the USB/AUX socket and pins 4,5, 22,23 from the MULF to the USB/AUX socket.
