Abstract

A method and apparatus for map-updating of a navigation system by automatically generating point of interest (POI) data that is not registered and automatically generating a POP alias of POI data that is already registered, the method including: logging at least one piece of point of interest (POI) data if the POI data input in order to find a destination is not found in the navigation terminal; and registering the logged at least one piece of POI data as a candidate POI alias of newly input POI data if a destination designated by the navigation terminal according to the newly input POI data is equal to an arrived destination.
