A navigation apparatus having a GPS receiver obtain coordinates of the current position. A key point or points close to the current position are retrieved from a recording medium attached to the apparatus. The distance and direction from the current position with respect to the retrieved point are computed. The name of the retrieved point is then displayed along with the distance and direction with respect thereto.

A simplified navigation apparatus to be mounted on a vehicle, comprising: a global positioning system (GPS) receiver for producing a global coordinate data signal representing the absolute current location of said vehicle; reading means for reading from a recording medium carrying thereon a plurality of geographical point data pairs, each data pair consisting of a point name data signal and a geographic coordinate data signal associated with said point name data signal; display means for displaying display information signals supplied thereto; display point setting means for selecting a geographical point data pair having a geographic coordinate data signal which is closest to said current vehicle position from said plurality of geographical point data pairs and for setting said geographic coordinate data signal as a display target point; reading control means for controlling said reading means so as to retrieve from said recording medium a point name data signal of the selected geographical point data pair; computing means for obtaining data regarding distance and direction from said absolute current location of said vehicle up to said display target point on the basis of the coordinate data signals of both of said absolute current location of said vehicle and said display target point; and display control means for supplying said display means with the retrieved point name data signal and the obtained distance data and direction data as said display information signals.
