Abstract
There is provided a map information display apparatus comprising a control unit, responsive to a signal informing that a predetermined area on a display unit has been indicated, for switching a display from a state of displaying a single map image on the screen in scroll mode in which the center of the map image constantly shows the current position of the vehicle detected by a position detecting unit and the map image is scrolled as the vehicle travels to a state of displaying a first map image with the same scale as the single map image which has been displayed on the screen in a base screen region and a second map image with a scale in a window screen region. Furthermore, touching an area of the base or window screen region switches the display into single display mode. Thus, switching between single display mode in which a single map image fills the screen of the display unit and parent display mode in which two map images associated with each other are respectively displayed in the base and window screen regions can be accomplished without having to use a mechanical switch.
