An input unit for navigation systems which easily inputs positional information for a destination point and so on. When discrimination information for a designated section of a map is input by an input device and representative points of the section and a certain point within the section are designated by using a transparent tablet overlaid on the map, a CPU, by reference to a map data base, calculates the geographic coordinates of the designated point within the designated section, based on the geographic coordinates of the representative point(s) of the section, and based on all positional information which is output from the transparent tablet and which corresponds to the representative point(s) of the section and the designated point within the section, and transmits the geographic coordinates of the designated point to a navigation device ECU.
