The navigation unit supports the driving of the vehicle. The mixer synthesizes the voice output of the voice synthesis circuit, audio signals from the DVD playback unit and audio signals from the navigation unit. The IR circuit converts the synthesized audio signals into IR signals. The headphones receive the IR signals from the IR circuit and convert the IR signals into audio.
