Destination search support device, methods, and programs
First Claim
1. A destination search support device usable in a navigation device, comprising:
- an information storage unit that stores a plurality of destination candidates for which search expiration dates are set; and
a controller that;
inputs a search term;
searches among the destination candidates in the information storage unit for the destination candidates that correspond to the search term;
sets one of the destination candidates that is found by the search as a destination;
extends the search expiration date for the destination candidate when the controller sets the destination candidate as the destination within a specified period before the search expiration date that is set for the destination candidate; and
deletes from the information storage unit the destination candidates for which the search expiration dates have passed.

Abstract
A navigation device, when a destination candidate is deleted, postpones the deletion by providing a deletion deadline for the destination candidate. This makes it possible to search for the destination candidate even if it is eligible for deletion. If a user sets as the destination a destination candidate whose deletion has been postponed, then the destination candidate is displayed differently to make the user aware that the deletion has been postponed. If a destination candidate for which the deletion deadline has been set is set as the destination, then the navigation device compares the deletion deadline to a date that is m months after the current date, and if the m months later date is later than the deletion deadline, the navigation device extends the deletion deadline by updating it to the m months later date. This postpones the deletion of a destination candidate that the user considers necessary.
