Abstract
A land vehicle navigation apparatus provides a present location map and various easily understood guidance information items in conformity with the environmental criteria of a route. The navigation apparatus includes information storage for storing map data as to route search, route guidance, and other guidance data, a present position detector for detecting the present position of the vehicle, an input device for inputting commands and information for route search and route guidance, and a display monitor unit for displaying a guidance screen with a map and other information relating to the route search and route guidance in a one-screen mode, or in a multiple-screen mode. A display controller responds to an input command via the input device, reads guidance data from the information storage, and controls the display of resultant read data on the display unit. Changes between the one-screen mode and the multiple-screen mode may occur with the screen of the one-screen mode of the display corresponding to one screen of the multiple-screen mode and a present-location map screen corresponding to another screen.
