You are looking at two different modules in that photo:

- the top module is Telephone/Telematics Control Unit (TCU)
- the bottom module is the MULF (Hi or Low)

The TCU is the GSM Telematics unit that handles ConnectedDrive/BMW Search communications, Bluetooth phone calls and Assist calls. The new Bluetooth Audio feature is there.

The MULF handles Bluetooth when there is no TCU installed. The MULF High handles the USB/6FL/6NF as well and the MULF Low just the Bluetooth.

Never read the name COMBOX referring to either the TCU or the MULF. Must be an UK thing...
