BLUETOOTH Phone Module (Bpm): Function: Phone
The system is a handsfree system which allows the customer to control their own cellphone from the vehicle and allows the customer to use the vehicle audio system during calls.
The following telephone functions are available via the vehicle's buttons and display when a cellphone is connected to the bluetooth phone module (BPM) via bluetooth:
- Receive incoming calls with number presentation
- End telephone calls
- Initiate telephone calls via normal number dialing
- Searching and initiating calls from the cellphone address book
- Accessing last number dialed/received/missed calls on the cellphone
- Activating voice activated function in the cellphone
- Transfer of sound between the vehicle's audio system and the cellphone can occur without interrupting the call.
The bluetooth phone module (BPM) has no keypad of its own for menu management but is either controlled via the keypad on the Climate control module (CCM) or via the steering wheel buttons. Climate control module (CCM) transmits the signals for menu management to the infotainment control module (ICM) via the CAN network. The infotainment control module (ICM) then transmits the signals onward to the Bluetooth phone module (BPM) via the MOST network.
When using the menu via the steering wheel buttons, information is transmitted from the steering wheel module (SWM) to the infotainment control module (ICM) via LIN communication. The information is then transmitted to the bluetooth phone module (BPM) via the MOST network.
Menu management is displayed for the user in the display for the infotainment control module (ICM). Information is transmitted from the Bluetooth phone module (BPM) to the infotainment control module (ICM) via the MOST network.
When starting the Bluetooth phone module (BPM), receiving incoming calls or when using the phone, a request to use the display will be transmitted to the infotainment control module (ICM).
During conversations via handsfree the microphone and speakers which are connected to the Audio module (AUD) and Integrated Audio Module (IAM) are used. Bluetooth phone module (BPM) transmits a request to the Infotainment control module (ICM) to receive access to the speakers and microphone. The infotainment control module (ICM) transmits the request onward to the Audio module (AUD) and Integrated Audio Module (IAM). The communication between the Bluetooth phone module (BPM), infotainment control module (ICM), Audio module (AUD) and Integrated Audio Module (IAM) occurs via the MOST network.
