Input the direction and distance of the destination from the point by referring to the map, display the starting point, destination, and a straight line connecting them on the display board, input any check points along the way if necessary, and start driving. Systems have already been developed that continuously display the vehicle's current position, direction of travel, and travel trajectory in relation to hourly travel distance and absolute heading on a display board (for example, Japanese Patent Laid-Open No. 142217/1983). (see official bulletin).
