AbstractA road map display system for an automotive vehicle displays a mark representative of a vehicle's position and direction. The mark is positioned at the center of a display screen and the coordinate system of the map is transformed depending on the vehicle's direction so that the mark indicative of the direction is always directed upward along the y-axis of the display. The system further includes a scale selector which is manually operable. Depending on the selected map scale, the displayed map is magnified or reduced.
