ABSTRACT:
A method and apparatus for a navigation system to update unfinished destinations set in the navigation system when one or more destinations have not been reached within a predetermined time limit. The method includes the steps of inputting one or more destinations in the navigation system, measuring a time passage for each destination starting from a time when the destination is set in the navigation system, comparing the measured time passage with a predetermined time limit which is a time length commonly applied to all of the destinations and reporting the user that the destination is expired when the time passage exceeds a predetermined time limit, and deleting or renewing the expired destination in response to the user's instruction. When the expired destination is renewed, a time passage for the renewed destination is newly measured from a time of the renewal.
