Abstract
A navigation apparatus including a position detector for detecting an vehicle's position and outputting vehicle's position data, a memory for storing map data, a display unit for displaying a variety of information, and a display controller for displaying a map on the display unit based on the map data and superimposing the vehicle's position on the map displayed on the display unit based on the vehicle's position data. The apparatus further includes a commander for specifying an arbitrary position on the map displayed on the display unit; a coordinate calculator for calculating the latitude and longitude as the coordinates of the actual location corresponding to the specified position on the map and outputting the same as coordinate data; and a coordinate display controller for superimposing the coordinates of the actual location in numerical values on the displayed map based on the coordinate data.
