HD radio™
- When the CMU receives the operation signal/detects the switch operation, it sends (1) the control signal to the remote tuner (RT).
- When the remote tuner (RT) receives the control signal, it switches (2) the tuner in the remote tuner (RT) to radio mode and initiates reception of the radio broadcast.
- The remote tuner (RT) detects the radio broadcast of the radio station selected by the user using the tuner in the remote tuner (RT) based on the electrical signal received (3) from the center roof antenna. The audio signal of the detected radio broadcast is sent (3) to the speakers. In addition, the detected radio broadcast logo or album is converted to a RS485 signal and the signal is sent (3) to the CMU.
- The CMU converts the RS485*12signal from the remote tuner (RT) to a GMSL signal and sends (4) the GMSL signal to the center display.
- The speakers output (5) the audio based on the audio signal received from the remote tuner (RT). In addition, the center display indicates HD radio™ information based on the GMSL signal.
