1. A map display apparatus that displays a map, comprising:
- a display device;
a touch panel disposed over a screen at the display device; and
a control device that controls display at the display device with a signal input from the touch panel, wherein;
the control device displays at the display device a map and a plurality of buttons used to adjust a scaling factor of the map, makes a decision as to whether or not the touch panel has been pressed at a position corresponding to one of the plurality of buttons, makes a decision as to whether or not a finger having pressed the touch panel has been moved to a specific position and displays, together with the map, a wide-area map at a scaling factor smaller than the scaling factor of the map if the finger having pressed the touch panel is judged to have been moved to the specific position.
