Brief Description Of Components: Notes

The TCU consists of the modules:

• Transmitter/receiver unit
• GPS receiver
• Aerial selector
• Bluetooth module

The TCU supports the following functions:

• Telematic services
• Bluetooth connection of customer's mobile phone

For more information, refer to TELEMATIC CONTROL UNIT (US): E60, E61, E63, E64, E90 .

The BMW radio "Professional" is part of the basic equipment specification of the E90. The radio serves as the gateway (data interface) between the MOST bus and the KCAN.

On the E90, the telephone is only available in conjunction with one of the following options:

• BMW radio "Professional" (RAD2)
• Car Communication Computer (CCC)

On the E60, E61, E63 and E64, M-ASK is installed in the basic equipment specification.

In this case, M-ASK is the interface for operating the telephone. The telephone directory and other information are shown on the Central Information Display (CID).

The CCC is installed in connection with one of the following options:

• Navigation system "Professional"
• "Voice recognition system"

Several control units and the CD-ROM/MD/DVD players are integrated into a single housing. The CCC is used to control all information and communication systems, including the telephone.

The menus for the M-ASK and CCC are displayed on the CID.

The base plate with snap-in adapter must be retrofitted by the dealer organization. The snap-in adapter is used as a bracket for the mobile phone so that a call can be made during a journey. The base plate includes the battery charger for the mobile phone.

For more information, refer to BASE PLATE WITH SNAP-IN ADAPTER: E60, E61, E63, E64, E90, E91 .

The customer is able to use his mobile phone, provided this is supported by BMW. Snap-in adapters are available for various bluetooth-compatible mobile phones.

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

If option 620 "Voice recognition system" is fitted in conjunction with the CCC, a second microphone is also fitted. This microphone is also located in the roof function center and is used to input voice commands. All CCC functions can then be operated using voice commands.

If option 620 is not fitted, only the telephone function can be operated using voice commands.

For more information, refer to MICROPHONES FOR HANDS-FREE MODE AND VOICE RECOGNITION: E60, E61, E63, E64, E90, E91 .

The emergency call button is located in the front headlining, in the middle next to the sliding/tilting sunroof switch. The emergency call button is used to manually trigger an emergency call. The emergency call button contains 1 LED and is protected against inadvertent pressing by a flap.

The buttons for the telephone functions are located on the MFL. When a call is accepted, the TCU (Telematic Control Unit) will switch to hands-free mode.

The following functions are operated by pressing the transmit/receive button:

• Accept or end call
• Select phone number from the following lists:
  • Telephone directory entries A - Z
  • Top-8 list (list of the 8 most frequently called phone numbers from the telephone directory entries A - Z)
  • Dialled numbers (list with last 10 phone numbers dialled)
  • Show missed calls
  • Show accepted calls
• Redial if no list is displayed. Redial will always be selected if the transmit/receive button is pressed and held.
• Pressing the button will automatically activate the voice recognition system in the TCU. With option 620 "Voice recognition system" the CCC's voice recognition system will be activated.

Aerials with the following aerial systems can be fitted for reception of mobile phone networks and GPS signals:

• SDARS aerial, includes the following aerials:
  • Telephone aerial 1
  • Telephone aerial 2
  • GPS aerial
  • SDARS aerial for terrestrial reception
  • Aerial for satellite reception
• Telephone and GPS aerial, includes:
  • Telephone aerial 1
  • Telephone aerial 2
  • GPS aerial
  • The GPS aerial picks up GPS signals. In the event of an accident, the GPS signals are used to compute the location of the vehicle if no navigation system installed.

An emergency call can be transmitted via the emergency antenna if the external telephone and GPS aerial or SDARS aerial is no longer operational, e.g. due to an accident.

For more information, refer to EMERGENCY ANTENNA: E60, E61, E63, E64, E90 .

If an emergency call is activated and voice output via the loudspeakers in the vehicle is not possible, the system will switch to the emergency loudspeaker. The emergency loudspeaker is connected directly to the TCU (Telematic Control Unit). The emergency loudspeaker is located in the driver's footwell.

The compensator equalizes losses in the aerial cable. The compensator can be retrofitted at the customer's express. This will improve reception.

For more information, refer to LINE COMPENSATOR (US): E60, E61, E63, E64, E90 .

The TCU communicates with the mobile phone via the bluetooth aerial.

For more information, refer to BLUETOOTH ANTENNA: E60, E61, E63, E64, E90, E91 .
