Abstract

A navigation system for guiding a vehicle to a destination in accordance with a predetermined route composed of roads and branching points. A data base stores the names of the roads, the names of the branching points, and information relating entry roads to exit roads. A first picture display is a route information screen listing at least the road names and the branching point names, which screen may be called up by a screen operating signal issued from an input switch. A controller reads the route information from the data base in response to the screen operating signal from the input switch and forms the listing displayed on the route information screen.
