Abstract: PURPOSE: To make the direction of the goal easy to find, and improve the clearness of a display and the easiness of judgment of traveling route. CONSTITUTION: The goal inputted by a driver is read (S10), the present position of a vehicle is calculated (S20), and the direction of the goal seen from the present position is calculated (S30). A map data is read (S40), and the coordinate of the map data is converted (S50) so that the direction calculated in S30 is conformed to just the upper part of a display screen. A mark (vehicle mark) showing the present position and advancing direction of the vehicle is superposed and displayed on the map data after the coordinate conversion (S60), and the present position and advancing direction of the vehicle are recalculated until the vehicle reaches the goal to move the vehicle mark on the display screen (S70, S80). Once the direction of the goal is first calculated, the direction is never recalculated even when the vehicle is moved.  Thus, the map is never rotated according to the movement of the vehicle.
