- with CODE (529) HIGH Class Japan


Function requirements
^ Status "Circuit 30 ON" or "Circuit 15R ON"
^ A compatible mobile phone has been inserted into the preinstalled cell phone separation point (X39/37) and is therefore connected to the COMAND controller unit (A40/3)
^ One mobile phone network is available in sufficient strength and quality
^ Mobile phone with Bluetooth capability in vehicle and authorized at the COMAND controller unit

To ensure that a mobile phone with Bluetooth capability that also authorized at the COMAND controller unit can be used in the vehicle, the mobile phone must support handsfree profile (HFP) 1.0 or 1.5. More information is available under:

General
For status "circuit 30 ON" the COMAND controller unit has to be manually switched on so that the mobile phone is switched on via a wake-up pulse from the COMAND controller unit.
For status "circuit 15R ON" the COMAND controller unit is automatically switched on; this in turn also automatically switches on the mobile phone by means of a wake-up pulse from the COMAND controller unit.
The mobile phone can be switched off at status "circuit 30 ON" by manually switching off the COMAND controller unit, which sends a corresponding signal to the mobile phone, or following expiration of the run-on time as configured on the mobile phone.
The mobile phone is switched off automatically at status "circuit 15R OFF" by the COMAND controller unit, which sends a corresponding signal to the mobile phone, or following expiration of the run-on time as configured on 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 forwarded by the COMAND controller unit as follows to the mobile phone:
- 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 if the mobile phone is so configured and transmits this status.
The lock code inquiry is forwarded by the COMAND controller unit via the telematics CAN to the COMAND display (A40/8) and via the central CAN to the multifunction display (A1p13) in the instrument cluster (A1).
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 center console button group (S148)

The control signals of the mobile phone buttons are forwarded via the following route to the COMAND controller unit:
- Adapter cable
- Cell phone separation point
- Direct line

The control signals of the center console button group telephone buttons are transferred to the COMAND controller unit via the following route:
- COU [ZBE] LIN
- Front central operating unit (A40/9)
- Telematics CAN

The reception status is shown by the COMAND controller unit on the COMAND display. After entering the lock code, the reception status with model 216 is forwarded to the COMAND control unit via the telephone and GPS antenna (A2/49) and with model 221 via the telephone and GPS roof antenna (A2/49):
- Direct line
- Cell phone separation point
- Direct line

A mobile phone operated with Bluetooth processes the switch-on signal internally in the mobile phone. The lock code inquiry is only shown on the display of the mobile phone, if configured on the mobile phone and if the mobile phone transmits this status. 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 is forwarded by the COMAND controller unit to the mobile phone via the following route:
- Direct line
- Cell phone separation point
- Adapter cable

The mobile phone is then switched off and power supply interrupted. Expiration of the run-on time configured in the mobile phone takes place internally in the mobile phone.

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.
