- When the connectivity master unit (CMU) receives the operation signal/detects the switch operation, it sends the control signal to the remote tuner (RT).
- When the remote tuner (RT) receives the control signal, it switches the tuner inside the remote tuner (RT) to radio mode and initiates reception of radio broadcasts.
- The remote tuner (RT) detects the radio broadcast from the received electric signal from the DAB antenna amplifier, at the tuner in the remote tuner (RT).
- The audio signal of the detected radio broadcast is sent to the speakers. In addition, the frequency of the detected radio broadcast is sent to the connectivity master unit (CMU).
- The connectivity master unit (CMU) converts the radio broadcast received from the remote tuner (RT) to a GMSL signal and sends the GMSL signal to the center display.
- The speakers output the audio based on the audio signal received from the remote tuner (RT). In addition, the center display indicates music information (song name/artist name) based on the GMSL signal.
