Can be configured to transmit).

In this case, the display unit 300 is configured to automatically display the initial image data repeatedly on the touch screen 350 if the first image data is not received after receiving the first image data. The first change image data is repeatedly displayed until the second change image data, which is data, is received.

In this case, when the signal output from the display panel 120 output unit is first converted into image data for the display unit 300 and transmitted to the display unit 300, for example, the audio device is operated by a specific signal of the handle remote controller 400. This is when the operation of the audio device is started, such as when there is a touch input to the audio control mode area on the screen of the touch screen 350 of the display unit 300.

Meanwhile, the update command of the display unit 300 is transmitted to the control unit 200 when a touch operation or a screen display error occurs on the screen of the touch screen 350 as one embodiment of the present invention.

When the navigation function is built into the display unit 300 in the audio control apparatus of the present invention, the control unit 200 transmits a 'mute' command to the command input unit during voice guidance of the navigation or the external sound output terminal of the display unit 300. When connected to the external sound (AUX) input terminal of the audio device, the control unit 200 may be configured to transmit a switch command to the external sound (AUX) mode to the command input unit when guiding the navigation.
