^ One mobile phone network is available in sufficient strength and quality
^ Mobile phone adapter cable connected via cell phone separation point (X39/37) to communications control unit (N123/6)
^ Compatible mobile phone connected to pre-installed adapted cable or bluetooth-compatible mobile phone in vehicle and authorized by COMAND operating, display and controller unit (A40/3)
Various mobile phones can be connected to the communication control unit over the portable CTEL separation point using the pre-installed adapter cable.
A bluetooth-compatible mobile phone can only be operated in the vehicle when a mobile phone is not connected to the portable CTEL separation point or the adapter cable.
To be able to operate a Bluetooth-capable mobile phone authorized at "audio equipment" in the vehicle, the mobile phone must support Hands Free Profile (HFP) 1.0 or 1.5. More information is available under:

General
When "Circuit 30 ON", the COMAND operating, display and controller unit must be switched on manually for the mobile phone to be switched on by a wake-up pulse from the COMAND operating, display and controller unit.
When "Circuit 15R ON", the COMAND operating, display and controller unit is switched on automatically and therefore the mobile phone is also switched on automatically by a wake-up pulse from the COMAND operating, display and controller unit. The mobile phone can be switched off with status "circuit 30 ON" by manually switching off the COMAND operating, display and controller unit, which sends a corresponding signal to the mobile phone.
The mobile phone is switched off automatically with status "circuit 15R OFF" by the COMAND operating, display and controller unit, which sends a corresponding signal to the mobile phone.
A mobile phone operated with Bluetooth can be switched on and off only with the buttons on the mobile phone itself.
The switch-on and switch-off function consists of the following two subfunctions:
^ Switch on function sequence
^ Switch off function sequence
Switch on function sequence
The switch-on signal (wake-up pulse) is routed to the mobile phone by the COMAND operating, display and controller unit over the following path:
- Direct line
- Communication control unit
- Direct line
- Cell phone separation point
- Adapter cable
The mobile phone is then switched on and supplied with power. After the mobile phone is switched on, a lock code inquiry is made the mobile phone is so configured and sends this status. The lock code inquiry is forwarded by the COMAND operating, display and controller unit to the display on the COMAND operating, display and controller unit as well as to the multifunction display (A1p13) in the instrument cluster (A1) over the interior CAN.
Depending on the request concerned the lock-code must be entered by one of the following options:
- Buttons on the mobile phone
- Telephone buttons on COMAND operating, display and controller unit
The control signals from the mobile phone buttons are transferred to the COMAND operating, display and controller unit over the following path:
- Adapter cable
- Cell phone separation point
- Direct line
- Communication control unit
- Direct line
The control signals from the telephone buttons on the COMAND operating, display and controller unit are processed internally. After entering the lock code, the reception status is received by the telephone antenna (A2/93a3) from the COMAND operating, display and controller unit over the following path:
- Direct line
- Cell phone separation point
- Direct line
- Communication control unit
- Direct line
The reception status is indicated by the COMAND operating, display and controller unit on the display of the COMAND operating, display and controller unit.
A mobile phone operated with Bluetooth processes the switch-on signal internally in the mobile phone. The lock code inquiry, if set on the mobile phone and it sends the status, is indicated on the mobile phone display only. The lock-code can only be entered using the mobile phone buttons. The reception status is received by the mobile phone's antenna. The display of the lock-code and the reception status as well as the signals of the mobile phone buttons are processed internally in the mobile phone.
Switch off function sequence
The switch-off signal (corresponding signal) is forwarded by the COMAND operating, display and controller unit to the mobile phone over the following path:
- Direct line
- Communication control unit
- Direct line
- Cell phone separation point
- Adapter cable
The mobile phone is then switched off and power supply interrupted.
A mobile phone operated with Bluetooth processes the switch-off signal internally in the mobile phone. If the rechargeable battery of the mobile phone is empty, the mobile phone is also switched off. This process also runs internally in the mobile phone.
