Introduction
The identifying feature of option 644 "Basic fittings for mobile phone with bluetooth interface" is the "universal charger and hands-free facility" (ULF).
The ULF serves to connect the bluetooth-compatible mobile phone to the vehicle's electrical system. The ULF control unit is connected to the MOST bus (Media-Oriented System Transport).
The ULF does not contain its own transmitter and receiver module for GSM communications (GSM: Global System for Mobile Communication). This function is only contained in the customer's mobile phone.
[system overview ...]
Important: from 03/2007: TCU and ULF-SBX-H can be fitted at the same time.
From this point in time on, the two control units can be fitted at the same time.
The interface box High (ULF-SBX-H) then serves solely option 6FL "USB audio interface". The telephone function is not available in the ULF-SBX-H. The TCU provides the telephone function.
Please refer to function description in BMW diagnosis system under "Telephone".
Information about bluetooth mobile phones approved by BMW is available from the BMW Parts Department. There, you will find a compatibility matrix.
This compatibility matrix will be updated at regular intervals in the BMW Group InfoNet.
Further information about how to sign a bluetooth mobile phone onto the ULF control unit can be found by following the link below.
The benefits of the universal charger and hands-free kit are:
- The driver is prohibited by law from making a phone call with the mobile phone in his hand while he is driving. However, phone calls can conveniently be made using the hands-free system.
- The bluetooth connection is automatically established between vehicle and mobile phone.
- Speech processing, allowing telephone operation in hands-free mode:
- Select a phone number from the telephone directory
- Make a connection
- Accept a phone call
- If the vehicle is equipped with the Car Communication Computer (CCC): The telephone functions can only be operated in hands-free mode using option 620 "Voice recognition system". Other CCC functions can then be operated using voice commands.
- Transmit and receive via the vehicle's external aerial. The occupants receive less exposure to electromagnetic fields.
- Charging mobile phone battery
Option 644 is not included and must be retrofitted by the customer:
- Bluetooth mobile phone
- Snap-in adapter
All bluetooth mobile phones that are supported by BMW can be used with option 644. These mobile phones have been checked with regard to suitable software. BMW Parts Department has a current compatibility matrix.
The matching snap-in adapters are available from the BMW Parts Service, e.g. for the following mobile phones (see compatibility matrix):
- BenQ - Siemens S55, S65, S75
- Sony Ericsson T610, T630, K750i, K800i
- Nokia 6310i, 6230i, 6233
- Motorola V600, V635
Brief description of components
The following components are involved in the ULF:
- Universal charger and hands-free kit 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
- 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.
- 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.
- 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.
- Compensator (optional)
The compensator equalises 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 unfavourable.
- 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.
- 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.
- 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"
- Option 620 "Voice recognition system"
- Option 601 "Video module"
- CID: Central Information Display
The menus for the M-ASK and CCC are displayed on the CID.
- Hands-free microphone and microphone for voice commands
The hands-free microphone is located in the roof function centre 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 centre. All CCC functions can then be operated using voice commands.
> E64, E93: The microphones are installed on the steering column.
Note: From 09/2006, only 1 microphone is to be fitted. This change will be introduced gradually through the various model series.
- 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
- Dialled numbers (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.
System functions
The functions needed for making a phone call with a mobile phone and ULF are based on wireless data transmission with bluetooth radio standard.
Functions inside the vehicle -
- Automatic prioritisation for establishing connection to mobile phones according to list of mobile phones signed on
- Hands-free mode with
- Full duplex transmission, both partners are able to talk and listen at the same time (without restriction at speeds of up to 130 km/h)
- Echo compensation (suppression of background noises)

Basic settings
- Signing mobile phone on to ULF control unit:
- 4 bluetooth mobile phones may be signed on to the ULF control unit at the same time.
- However, the mobile phones can be only be used one at a time. Here, a mobile phone at the top of the list has priority over the mobile phone further down.
Coupling assistant
A coupling assistant is available since 03/2007: Please refer to the Owner's Handbook.
In order to give the customer better support when coupling bluetooth mobile phones to the vehicle, the menu in the Central Information Display (CID) has been restructured. Here, the menu has been extended by the inclusion of a coupling assistant.
The coupling assistant includes the following features:
- Step-by-step instructions for the entire coupling process on the Central Information Display (CID)
- Detailed help texts and instructions for additional support in case the coupling process is not successful.
Coupling comprises four steps:
1. Bluetooth activation
2. Coupling
3. Passkey input
4. End coupling
Vehicles with BMW "Professional" radio also have a coupling assistant.
