In the car audio / AV system configured as described above, for example, when listening to a radio broadcast, music, or playing a video, the display unit mounted on the front panel of the car audio system is typically used for car audio / AV. Is a function mode display unit for displaying a mode in which is currently operated, a modulation mode display unit for displaying a modulation method when receiving radio, a reception frequency display unit for displaying a currently received broadcast frequency, and a unit of frequency displayed in the reception frequency display unit. It consists of a frequency unit display part to display.

The panel display in the existing car audio / AV system having the above configuration, that is, the screen provided by the display unit provides only the fixed screen set in the initial MICOM. In addition, when listening to music or the like, the operation display screen provided through the de-play unit also provides only the fixed screen set in the initial microcomputer as described above.

As described above, the car audio / video system is fixed to a basic screen provided by the display unit, such as a background screen or an operation display screen, only to a specific screen set at the time of initial production of the system. Therefore, such a setting is fixed, and thus, the user can not change the background screen arbitrarily, and there is a problem that only the screen generated by the producer can be maintained as it is. There is a problem that can not give a visual effect to the user by providing only a fixed screen configuration as described above.
