Abstract
A map display control apparatus for a motor vehicle including a road map storage device which stores road map data relating to a road map. A bird'"'"'s-eye view data converting circuit converts the road map data into bird'"'"'s-eye view data so that the road map is displayable on a display device according to a bird'"'"'s-eye view method in which the road map is obliquely looked down from above. A display control circuit controls the display device to display the road map according to the bird'"'"'s-eye view data on the display device, wherein the display control circuit controls the display device to display an image representative of a sky in a part of the display device that is close to an upper side of a display screen of the display device.
