A navigation system includes input means (1a) for entering a telephone number; an information storage device (3) for storing telephone-number data (3a), in which a location name inclusive of a set of coordinate is stored for each telephone number, address data (3b) in which an address is stored for each set of coordinates, and map data (3c); a central processor (4) having telephone-number retrieval means (4a) for retrieving, from the information storage device, location coordinates and location name of a telephone number entered by the input means, and address-data retrieval means (4b) for retrieving address data corresponding to the location coordinates of the telephone number entered by the input means; and display means (1b) for displaying a location name and address, which have been retrieved by the central processor, as well as a map centered on the location. Designation and entry of a location are performed by displaying the location name and address retrieved by entry of a telephone number, as well as the map centered on said location, on the display means. Since the amount of data is broken up into the telephone-number data and address data, the amount of telephone-number data can be reduced.
