It has been known. In such an in-vehicle navigation device, designating or changing a map display position with a remote controller and a touch panel has been performed.

In a conventional in-vehicle navigation device, when a user specifies a point on a map with a pinpoint to set a destination, register a point, check a road, or the like, the user scrolls the map or enlarges or reduces the map. There is. In such a case, a pointer which is a mark appearing on the screen is used. This pointer is always located at the center of the screen as shown in FIG.

[0004] The pointer is made to coincide with the point on the map at which the pinpoint is designated. At this time, the map is scrolled without moving the pointer. To scroll, use 4, 8 or 1 on the remote control
The scroll direction is designated by the six-way buttons and the joystick. For example, if the user wants the map display center position (pointer position) to be to the left of the current display, the user presses a left direction designation button or operates the joystick to the left.

When the scroll direction is designated on the touch panel, the display position is scrolled to the left by touching the left portion of the center of the monitor. Also, if a part below the center is touched, the display position scrolls downward. And
