Function requirements 

IMPORTANT Various mobile phones can be connected to the communications control unit over the cell phone separation point using the preinstalled adapter cable.

IMPORTANT A Bluetooth-compatible mobile phone can only be operated in the vehicle when a mobile phone is not connected to the cell phone separation point or the adapter cable.

IMPORTANT In order to be able to operate a Bluetooth-compatible mobile phone authorized at the COMAND operating, display and controller unit in the vehicle, the mobile phone must support the handsfree 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.

IMPORTANT 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:

Function sequence for switch on 

The switch-on signal (wake-up pulse) is routed to the mobile phone by the COMAND operating, display and controller unit via the following route:

The mobile phone is then switched on and supplied with power. After the mobile phone is switched on, a lock code inquiry is made if 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 of the COMAND operating, display and controller unit and to the multifunction display (A1p13) in the instrument cluster (A1) via the interior CAN (CAN B). Depending on the request concerned the lock-code must be entered by one of the following options:

The control signals from the mobile phone buttons are transferred to the COMAND operating, display and controller unit via the following route:

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:

The reception status is indicated by the COMAND operating, display and controller unit on the display of the COMAND operating, display and controller unit.

IMPORTANT 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 via the following route:

The mobile phone is then switched off and power supply interrupted.

IMPORTANT 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.
