The navigation apparatus includes a GPS receiver and a road data storage unit, and the input/output apparatus includes map drawing data storage unit, in which map drawing data related to coordinate data is stored, and a touch panel for displaying a map image. The navigation apparatus transmits coordinates of a vehicle location and direction to the input/output apparatus. The input/output apparatus reads map drawing data corresponding to the received coordinates and the direction from the map drawing data storage unit and displays the read map drawing data on the touch panel. The input/output apparatus marks the vehicle location on the touch panel in accordance with the coordinates of the vehicle location and direction.",
