Abstract
A navigation system has stored route information based upon longitude and latitude point coordinates for being retrieved and displayed to guide a user from a present position to a destination. The point coordinates of the destination are input to the navigation system by manual entry of the longitude and latitude point coordinates, by manual entry of a single multiple-digit alphanumeric code (G-code) containing combined longitude and latitude point coordinates, or by receipt of an external radio, optical, telephone or wire transmission of the longitude and latitude point coordinates from an information center or from a data storage medium such as a magnetic or electronic note card. The longitude and latitude point coordinates or the single multiple-digit alphanumeric code for manual entry can be read from a list of places or a map.
