Abstract
A display method and apparatus for a navigation system which is capable of easily and quickly showing the existence of a large structure within which a specific point of interest (“POI”) is located. The navigation system searches a desired point of interest as specified by a user, examines whether the point of interest is located within a large structure, searches an icon representing a type of the large compound in which the point of interest is located, and when a particular point of interest is located within a large structure, displays the icon of the large structure and the POI name on a monitor of the navigation system. Upon selection of the icon by the user, the navigation system displays detailed information on the large structure.
