Combox multimedia (CBX-MEDIA) and Combox emergency call (CBX-ECALL)
The Combox in the high equipment is a component with two integrated control units:
With High equipment, the Combox consists of 2 components:
- Main board: Combox multimedia (CBX-MEDIA)
- Emergency call printed circuit board: Combox emergency call (CBX-ECALL)
In principle, these are 2 separate control units in one housing. These two control units also respond during the vehicle test in the diagnosis.
If the CBX-MEDIA and the CBX-ECALL are fitted, the Combox has telematics capability.
The Combox multimedia (CBX-MEDIA) is a MOST device and is supplied with voltage via terminal 30B. The Combox emergency call (CBX-ECALL) is a CAN control unit and is supplied with voltage via terminal 30F.
NOTE: Note the colour coding of the 26-pin connector.
In the case of a Combox for the vehicle electrical system 2010, the 26-pin plug connection is white and for the vehicle electrical system 2000 it is black in order to provide an easy distinction.
Aerials
Different aerials are required for the functions telephone and telematics:
- Roof-mounted aerial with 2 telephone aerials and 1 GPS aerial
- Bluetooth aerial
- Emergency GSM aerial
- Telephone aerial, bumper
Roof aerial
The housing of the roof-mounted aerial contains the following aerials:
- Telephone aerial (GSM 1) for mobile phone
(GSM stands for Global Standard for Mobile Communications)
- Telephone aerial (GSM 2) for telematics services
- GPS aerial (optional)
(GPS stands for Global Positioning System)
Within the scope of certain optional equipment, further additional aerials which are not for the telephone or telematics may be installed in the roof-mounted aerial (e. g. Digital Audio Broadcasting, Satellite Digital Audio Radio Service).
Bluetooth aerial
Bluetooth aerial Among other things, there is a Bluetooth module installed in the Combox. The Bluetooth module is the interface between the Combox and the mobile phone and the Bluetooth handset. The Bluetooth aerial is connected with the Bluetooth module.
Since 03/2010 the previously installed Bluetooth aerial has been gradually replaced with a new Bluetooth aerial on all the series. The following graphic illustrates the Bluetooth aerial installed up to 03/2010.
The following graphic illustrates the Bluetooth aerial that has been gradually installed in all the series as of 03/2010.
Emergency GSM aerial
The emergency GSM aerial is secured to the storage shelf (can vary depending on vehicle type).
If the restraint systems are activated, the ACSM transmits a signal to the Combox. The control unit automatically initiates an emergency call, which also contains the location of the vehicle.
There is an aerial selector in the Combox (only where a CBX-ECALL is fitted). The aerial selector is used to switch over to the emergency GSM aerial if the GSM aerial in the roof-mounted aerial fails (e.g. due to an accident). Switch-over is carried out automatically if the GSM aerial in the roof-mounted aerial has poorer reception than the emergency GSM aerial.
If the vehicle is not fitted with a navigation system, the Combox emergency call is made via its own GPS module and its own connection to the GPS aerial. If the vehicle is fitted with a navigation system, the Combox emergency call is made from the headunit with the position data.
During an emergency call, the data is transferred to a server and stored. The data can be used by the service provider for initiating the rescue measures.
Telephone aerial, bumper
The bumper telephone aerial is the transceiver aerial for the rear compartment telephone. The bumper telephone aerial is fitted depending on the selected optional equipment.
A connection with the GSM network is established with the help of the bumper telephone aerial. The aerial is divided into a left and right section to reduce shadowing by the vehicle. The division of the aerial improves the receiving power.
SOS button with emergency call LED
The emergency call button with emergency call LED is directly connected with the Combox.
Triggering an emergency call:
- Touch the covering flap of the emergency call button and open it.
- Press the emergency call button until the emergency call LED lights up. The connection is established.
- When the emergency call LED flashes, the connection has been established.
The manual emergency call can be cancelled within 5 seconds.
The following graphic shows the emergency call button with emergency call LED in the roof function centre with the example F01.
Emergency loudspeaker
If an emergency call is made, the Service Provider endeavors to establish voice contact with the occupant. This voice contact enables the Service Provider to obtain further information about the accident (accident severity, number of people injured). This then enables the corresponding rescue measures to be initiated.
Whenever voice contact is established, the occupant is able to hear the Service Provider through the emergency loudspeaker.
The microphone on the driver's side is always used for the hands-free mode during an emergency call.
During a manual or automatic emergency call the sound output always takes place over the emergency loudspeaker.
Microphone and microphone 2
Depending on the series and the vehicle equipment, two hands-free microphones (microphone and microphone 2) are installed in the outer left and right sides of the roof-liner near the sun visors. The microphone installation location can vary depending on the vehicle type. The microphones are used for the hands-free mode during telephone operation. The microphone on the driver's side is always used for an emergency call.
The microphones work with full duplex transmission. This means that the audio frequency signals are activated for both parties. It is thereby possible to speak and listen during the same call.
The hands-free microphones are directly connected to the Combox.
If a Combox is not installed, the microphone will be omitted for the roofliner on the passenger side. The microphone for speech processing (if part of the equipment) in the roofliner on the driver's side is then directly connected with the headunit.
Front base plate
The base plate for mounting the mobile phone via the snap-in adapter is located in the centre armrest (with the optional equipment SA6NF extended connection of the music players in the mobile phone). Depending on the mobile phone used, a special snap-in adapter may be required. The snap-in adapter inserted into the base plate instead of the storage tray.
The mobile phone is charged and connected with the roof-mounted aerial via the snap-in adapter. A USB connection and an AUX-IN connection is also established with the vehicle. These functions can vary depending on the snap-in adapter. Information on available snap-in adapters and their functions can be found in the Electronic Parts Catalogue (ETK).
Depending on the vehicle equipment, the base plate will have an integrated video connection. The connection is for the playback of video files from a connected smartphone.
The snap-in adapters are only available for BMW Group approved mobile phones and can vary depending on the vehicle and equipment. A fitting snap-in adapter can be found in the Electronic Parts Catalogue (ETK).
NOTE: Base plate for rear compartment telephone.
For the optional equipment rear compartment telephone, there is one base plate for the mobile phone and handset in the rear centre armrest.
USB audio interface
The AUX-IN connection can be used to connect an external audio source (e. g. MP3 or CD player) via a 3.5 mm jack plug. The unit is operated on the operating elements of the external audio source.
All vehicles with a Combox are equipped with a USB and AUX-IN connection. External audio sources with USB port are integrated in the vehicle's entertainment system via this USB audio interface (switched). The operation of external audio sources via the USB port take place with the help of the controller on the central information display.
With the optional equipment SA6NF a second USB and AUX-IN connection is available via the base plate in conjunction with a suitable snap-in adapter.
A connection for smartphones is offered for connection of the MP3 player in the mobile phone (SA6NF extended connectivity of the music player in the mobile phone). With the connection, it is possible to transfer the music files, that are located on the smartphone, to the vehicle entertainment system via the Bluetooth connection.
USB hub
The USB hub contains an active USB signal amplifier. The USB hub has 2 inputs and 1 output for USB. The USB signal amplifier compensates for a power loss resulting from a cable extension of the USB connection. The USB hub is therefore only installed in vehicles where long cable lengths are used.
The USB hub has its own voltage supply on terminal 30B. This means that the USB hub can supply each device connected to the input with a current of up to 500 mA. The voltage transformer in the USB hub outputs a maximum of 5 V. The voltage is pending at the active USB signal amplifier and at the inputs.

Customer-initiated software update (KISA)
With the installation of the Combox, for the first time, the customer will be able to update the software of a specific system component (operation via menu in the central information display). To do this, the necessary software must be downloaded from http://www.bmw.de/update and stored on a USB stick. For this, a USB stick with sufficient storage capacity must be used. The software is then transferred from the USB stick to the Combox via the USB audio interface (SA6FL) in the centre console and automatically installed.
NOTE: Not all USB sticks are compatible with the vehicle. Use only BMW approved USB sticks.
For vehicles with TeleService (observe corresponding optional equipment) a software update is also possible via the service "Teleservice Update". By doing this, the software is transferred and installed via the Teleservice. The use of a USB stick is not necessary.
Notes for Service department
General notes
If a vehicle with Combox receives programming on the integration level, a manual subsequent software update via USB must be performed (vehicle with USB audio interface SA6FL). Whether a customer has already performed a software update can be ascertained via the workshop system. In this case, the software update must be carried out by the Service department employee when the Combox is replaced or programmed to integration level.
If a Combox emergency call is installed, an update of the online services must be performed after a control unit replacement or programming. This takes place through the service via the menu in the central information display.
NOTE: Checking of the Combox after an accident.
The housing of the Combox is designed for mounting without a holder. However, without a holder, in the event of a crash, the impact energy of the accident will be transferred directly to the control unit. In the event of an accident, the control unit must be checked for external damage.
