Mobile telephone system, general 

Equipment and use variants of mobile phone system:

All variants use Bluetooth® technology for data transfer.

IMPORTANT An authorized mobile phone can also be used as a modem for accessing the Internet or as a playback device as part of Bluetooth® audio.

The head unit sends and receives telephone signals over the Bluetooth® antenna. The head unit also generates display messages and transmits the corresponding data to the Audio/COMMAND display via the HSVL line. If the head unit is not switched on, it can be activated via the "ON" button in the respective lower control panel. The lower control panel transmits the status of the "ON" button to the head unit via the LCP-LIN, Audio/COMMAND control panel (except code 446 (Touchpad only)) or touchpad (with code 446 (Touchpad only)) and telematics CAN.

IMPORTANT The mobile phone system is described using the example of basic telephony. The special equipment features are summarized at the end of this document.

The mobile phone system includes the following areas:

Bluetooth® 

Using Bluetooth®, it is possible to quickly and easily connect mobile terminals that support the corresponding profiles to the mobile phone system. Bluetooth® is a worldwide open standard for connecting Bluetooth® devices (e.g. mobile phone) wirelessly and is based on radio technology in the 2.4 GHz range. One advantage of Bluetooth®, in addition to the wide availability of Bluetooth® devices, is the uncomplicated and spontaneous connection of Bluetooth® devices. The relatively high data security (128-bit encoding) and the relatively limited radius (approx. 10 m) of a Bluetooth® network also make the use of Bluetooth® in the vehicle interesting. The head unit can integrate mobile phones into the vehicle hierarchy over the mobile phone's Bluetooth® interface and the Bluetooth® antenna. The head unit automatically searches for the last two connected mobile phones and connects to the mobile phone that responds first.

IMPORTANT If the mobile phone is not connected with the head unit automatically or if the head unit is to establish a connection with a different mobile phone, the connection must be established manually via the basic telephone function. Authorized mobile phones can be selected from a list. Non-authorized mobile phones must be authorized first. Up to 15 mobile phones can be authorized at the same time. If a new mobile phone is to be authorized when there are already 15 authorized mobile phones, the user is prompted to delete one of the existing data records. Detailed information on authorization can be found in the respective operator's manual.

Switch on/off characteristics 

The mobile phone is switched ON/OFF via the mobile phone itself. The Personal Identification Number (PIN) must then, where set, be entered in the mobile phone. If the subscriber identification module (SIM) has been authorized, the mobile phone registers with the mobile phone network of the respective provider. The mobile phone network provider and signal level are displayed in the status bar of the Audio/COMMAND display. The Bluetooth® setting must be enabled in the mobile phone.

If the mobile phone was manually or automatically switched off or if the Bluetooth® setting is switched off, the message "Ready for Bluetooth® Telephony" is displayed on the Audio/COMMAND display. The head unit then searches again for the last authorized mobile phones.

The head unit can be switched on or off using the "ON" button on the respective lower control panel.

Call signal 

The head unit receives the call signal of the mobile phone via the Bluetooth® antenna. The head unit then switches the active audio source to "Mute" and shows the caller ID in the Audio/COMMAND display. To do this, the head unit transmits the corresponding data to the Audio/COMMAND display via the HSVL line. The ringing tone is output via the speaker system. The head unit activates the speaker system directly or transmits the corresponding signals to one of the following devices via MOST:

If the mobile phone supports in-band ringing, the ring tone of the mobile phone is output, a standard ring tone is otherwise output.

Establish, end, accept, reject or toggle call 

Telephone numbers can be entered using a character bar on the Audio/COMMAND display or they can be searched for and selected in call lists or in the address book.

The mobile phone system can be operated using the following components:

IMPORTANT The individual voice commands are listed in the "Linguatronic operator's manual".

IMPORTANT Call waiting: Call waiting is a performance feature in which the subscriber can switch between two active connections.

IMPORTANT Conference connection: Conference connection is a performance feature in which - depending on the type of connection - several subscribers can be interconnected.

Using the phone in hands-free mode 

The voice input in the hands-free mode is recorded by the hands-free system microphone and forwarded to the head unit. The head unit and the mobile phone communicate with each other via the Bluetooth® antenna. Incoming voice signals are output via the speaker system. The head unit activates the speaker system directly or transmits the corresponding signals to one of the following devices via MOST:

The volume of the voice outputs can be adjusted using the following control elements, for example:

Address book 

The user can manage all the contact data in the address book (view, edit, add, delete and create). The address book contains the address entries stored in the head unit. Address entries can only be removed by deleting individual entries or by deleting the entire address book. Address-relevant mobile phone system applications can be directly started and supplied with the stored data via address book entries. Address data of external devices (e.g. Personal Digital Assistant (PDA), Notebook) or storage media (e.g. Secure Digital (SD) card, Universal Serial Bus (USB) memory) can be saved in the address book and are then permanently available as an address entry.

Address data can be transferred to the address book via the following system components:

Address book entries can include the following information:

IMPORTANT Model 213 up to model year 2021 with code 498 (Japanese version)

The call can be established via the VCS [SBS] for each entry with a completed "Yomigana field".

SMS/email (except code 498 (Japan version)) 

The SMS/email application enables the user to receive, send or manage SMS messages and emails. To do so, the SMS messages and emails previously received on the mobile phone as well as any new incoming SMS messages and emails are forwarded to the head unit. The following SMS and email functions are available:

The SMS and email function with basic telephony requires support of the Message Access Profile (MAP). Under certain circumstances, loading SMS messages may take a long time. This may be because of the mobile phone or the number of SMS messages or emails in the mobile phone.

Once the head unit is connected with the mobile phone, it receives the SMS messages already saved in the mobile phone and any new incoming SMS messages and emails via the Bluetooth® antenna. The functions for writing, sending and managing SMS messages or emails are called up through the basic telephone function. The head unit shows them on the Audio/COMMAND display over the HSVL line. When reading out SMS and emails, the head unit actuates the speaker system directly or sends the corresponding signals to one of the following devices via MOST:

Telephony (with code 386 (Comfort telephony) or code 379 (telephone module with Bluetooth® (SAP)))
