The following components are involved in the ULF:

ULF control unit
The ULF control unit contains the components for the following functions
- Connection of mobile phone with bluetooth interface to the vehicle
- Regulated power supply to bluetooth mobile phone in snap-in adapter
- Communication between ULF control unit and display device in vehicle
For more information, refer to E60, E61, E63, E64, E87, E90: ULF CONTROL UNIT .
Base plate
The base plate provides the connection of the bluetooth mobile phone to the vehicle wiring harness and to the ULF control unit. The snap-in adapter is fitted to the base plate.

For more information, refer to E60, E61, E63, E64, E87, E90: ULF BASE PLATE .
Snap-in adapter
The snap-in adapter is the connecting piece between the base plate and the bluetooth mobile phone. The snap-in adapter creates the connection to the GSM aerial and to the vehicle electrical system. The snap-in adapter contains the battery charger for the mobile phone.

For more information, refer to E60, E61, E63, E64, E87, E90: SNAP-IN ADAPTER ON BASE PLATE .
Bluetooth mobile phone
The reverse of the mobile phone engaged in the snap-in adapter is connected to the aerial connector in the GSM aerial cable. The mobile phone's battery is supplied with charging voltage via the charging contacts.

For more information, refer to E60, E61, E63, E64, E87, E90: BLUETOOTH MOBILE PHONE IN SNAP-IN ADAPTER .
Compensator (optional)
The compensator equalizes losses in the aerial cable between the snap-in adapter and the GSM antenna. The compensator is only installed at the customer's express wish, e.g. if the operation conditions in a mobile phone network are unfavorable.

For more information, refer to E60, E61, E63, E64, E87, E90: COMPENSATOR .
GSM antenna
The GSM antenna (GSM: Global System for Mobile Communication) is the transmitting and receiving aerial for the mobile phone.

Because the GSM antenna is mounted on the outside of the vehicle, communication with the mobile phone network is improved. Moreover, vehicle occupants are less exposed to electromagnetic waves.

For more information, refer to E60, E61, E63, E64, E87, E90: GSM ANTENNA .
Bluetooth antenna
The bluetooth antenna is the transmit/receive aerial of the ULF control unit. Communication with bluetooth-compatible equipment is conducted through the bluetooth antenna.

For more information, refer to E60, E61, E63, E64, E87, E90: BLUETOOTH ANTENNA .
RAD2: Radio 2, sales designation: BMW radio "Professional"
The radio serves as the gateway (data interface) between the MOST bus and the K-CAN.
M-ASK: Multi-audio system controller
On the E60, E61, E63 and E64, M-ASK is installed in the basic equipment specification.
CCC: Car Communication Computer
The CCC is installed in connection with one of the following options:
- Option 609 "Professional navigation system"

Hands-free microphone and microphone for voice commands
The hands-free microphone is located in the roof function center and is used to input speech information and voice commands into the hands-free system.

On vehicles with CCC, option 620 "Voice recognition system" is also necessary, as voice commands cannot otherwise be processed. With option 620 "Voice recognition system", a second microphone for inputting voice commands is fitted in the roof function center. All CCC functions can then be operated using voice commands.

>E64: The microphones are installed on the steering column.
MFL: Multi-function steering wheel (optional)
The MFL has buttons that can also be used for operating the telephone. If a call is accepted, the ULF will switch to hands-free mode.

The following functions are operated by pressing the transmit/receive button:
- Accept or end call
- Redial (list with last 8 phone numbers dialled)
- Pressing the button will automatically activate the voice recognition system in the ULF. Vehicles with CCC: With option 620 "Voice recognition system" the CCC's voice recognition system will be activated.
