PURPOSE:To perform an accurate display, by a method wherein a quadrant, whereto a destination, whose starting point acts as an original point, belongs, is selected based on the bearing data of the destination, and the running trace of the vehicle of the quadrant is enlarged over a total surface of a display area for display. CONSTITUTION:A display picture of a CRT10 for displaying a running trace of a vehicle is divided into 4 areas, and an advancing direction area 200, a comment display area 300, a running distance, a residual distance display area 400, and a coordinate display area 500 are allotted. A quadrant of a destination, whose starting point acts as an original point, is selected based on a bearing data against the destination, and the running trace of the selected quadrant is enlarged over a total surface of a display area and is displayed in the coordinate display area 500. Then, a starting point is set to points A, B, C, and D according to each quadrant. This permits to perform an accurate running trace. |
