In step S155, when it is checked that the K2 button is pressed, after rotating the PIP mode, the POP mode, and the normal mode (step S160), the step S145 or less is performed.

If it is checked in step S155 that the K4 button is pressed, the main screen and the sub screen are switched in the PIP mode or the POP mode (step S165), and the step S145 or less is performed.

If it is checked in step S155 that the K3 button is pressed, it is checked whether the PIP button or the POP button is pressed (step S170).

If it is checked in step S170 that the POP button is pressed, after adjusting the size between the main screen and the sub screen according to a user's operation (step S175), the step S145 is performed. For example, when the POP button is pressed according to the user's operation, for example, as the button 1 is pressed, the size between the main screen and the sub screen is adjusted to 1: 1 as shown in FIG. 4A. It may be. In FIG. 4A, the main screen is a vehicle navigation map image, and the sub screen is various DMB images or PMP images.

In addition, in response to the user's manipulation of the POP button being pressed, for example, when the second button is pressed, the size between the main screen and the sub screen may be adjusted to 2: 1 as shown in FIG. 4B. . In FIG. 4B, the main screen is a vehicle navigation map image, and the sub screen is various DMB images or PMP images. Of course, the sub-screen may be located at the upper portion of the screen, at the interruption portion, or at the lower portion, depending on the user's manipulation.

If it is checked in step S170 that the PIP button is pressed, the position of the sub screen is moved on the main screen according to a user's operation (step S180), and then step S145 is performed. For example, when the first button is pressed while the PIP button is pressed according to a user's operation, the position of the sub screen on the main screen may be moved to the upper left side.

In addition, as the second button is pressed while the PIP button is pressed according to the user's operation, the position of the sub screen may be moved to the lower left side on the main screen.
