Abstract
A navigation system comprises: an antenna 12 which receives radio waves from a GPS satellite; a controller 15 which perform various operations to detect the present position of the car from the output signal of the antenna 12; and an image display 17 which, being controlled by the controller, displays a map, the present position of the car, etc., and a traveling-direction indicator 30 which includes a sign section made up of arrow marks or triangular marks to indicate a direction in which the car should move on. With the system, as the car comes near a branching guide point such as a crossing, the controller 15 operates to cause the sign section of the traveling-section indicator 30 to turn on or flicker to indicate a direction in which the car should move one.
