SMS (Short Message Service)
- When the CMU receives the operation signal/detects the switch operation, it sends (1) a control signal to a mobile device such as a Bluetooth®-enabled mobile phone or a Smartphone.
- When the mobile device such as a Smartphone or a Bluetooth®-enabled device receives the control signal, the digital data is sent (2) to the CMU.
- The CMU converts the video signal of the digital data to a GMSL signal and sends (3) the GMSL signal to the center display.
- The center display indicates the SMS information based on the received GMSL signal.
