Telephone switch-on/switch-off characteristics, general
In vehicles without code (386) Comfort telephony, the mobile phone must be switched on and off manually using the buttons on the mobile phone.
In vehicles with code (386) Comfort telephony the mobile phone is switched on automatically by a wake-up pulse when the audio equipment is switched on. The audio equipment transmits the wake- up pulse to the cradle via a direct line and the Bluetooth module.
The mobile phone is then supplied with power and switched on.
If configured on the mobile phone, the Personal Identification Number (PIN) is prompted (not with code Division Multiple Access (CDMA) network in USA).
The PIN prompt is displayed on the audio/COMAND display (A40/8) and the instrument cluster (A1).
The signals that are required for this are transmitted by the audio equipment via the Low Voltage Differential Signal (LVDS) line to the Audio/COMAND display and via the interior CAN (CAN B) to the instrument cluster.
In vehicles without code (386) Comfort telephony the PIN is prompted on the mobile phone itself. Appropriate instructions can be found in the equipment manufacturer's operating instructions.
The following possibilities are available for PIN entry:
- PIN entry via the control buttons on the mobile phone
- PIN entry via the control buttons on the audio equipment (with code (386) Comfort telephony)
- PIN entry via the audio/COMAND control panel (A40/9) (with code (386) Comfort telephony)
- PIN entry via the voice control system (VCS [SBS]) (with code (511) Audio 50 APS with DVD changer or code (527) COMAND APS with single DVD drive (with navigation) or code (512) COMAND APS with DVD changer) (with code (386) Comfort telephony)
The control signals of the control buttons on the mobile phone are processed internally by the mobile phone.
The control signals of the control buttons on the audio equipment are processed internally and forwarded to the mobile phone via the following route:
- Direct line
- Bluetooth antenna (A2/91)
- Bluetooth module
- Cradle
- Mobile phone
The control signals of the Audio/COMAND control panel are forwarded to the "audio equipment" via the telematics CAN (CAN A).
The audio equipment then forwards them to the mobile phone via the following route:
- Direct line
- Bluetooth antenna
- Bluetooth module
- Cradle
- Mobile phone
The voice signals from the VCS [SBS] are picked up by the handsfree system microphone (A67b1) and forwarded to the audio equipment via a direct line. The audio equipment then forwards them to the mobile phone via the following route:
- Direct line
- Bluetooth antenna
- Bluetooth module
- Cradle
- Mobile phone
After checking and enabling (not with "CDMA network" in the USA), the mobile phone logs itself into the service provider's mobile telephone network via the following route:
