Look in the bluetooth sticky for details.
Yeah I know, I just did finish the USB/Bluetooth retrofit with the MULF2. I was just commenting on your description where the audio goes through the Aux and the control of the iPod goes through the usb, that is the 6FL. There is also an iPod specific adapter that BMW sells that connects directly to the MOST bus, this method is completely digital.
