ABSTRACT:
A map displaying apparatus for displaying a map and a destination on a display screen. A map memory stores a map data to be displayed on a displayer. A telephone number, an area code, or postal code is inputted through an inputting panel. A second memory stores information on telephone numbers and the coordinates of positions on a map corresponding to the respective telephone numbers, information on area codes and the coordinates of positions on a map corresponding to the respective area codes, and information on postal codes and the coordinates of positions on a map corresponding to the respective postal codes. A position retrieval section reads from the second memory the coordinate of a position on a map corresponding to the telephone number inputted through the inputting panel, the coordinate of positions on a map corresponding to the area code inputted through the inputting panel, the coordinate of positions on a map corresponding to the postal code inputted through the inputting panel. The position retrieval section then retrieves map data stored in the map memory according to the telephone number, area code, or postal code and displays the map on the displayer. The map region on display may be shown highlighted when the map region is specified by information such as an area code and a postal code.
