- 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 selected by the user using the tuner in the remote tuner (RT) based on the electrical signal received from the center roof antenna. 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.
