Abstract:
1. A method for inputting data indicating a tentative destination for a navigation system, comprising the following steps of: allowing a user to specify an intended destination in the navigation system and searching address data indicating the intended destination in a map database of the navigation system; through a display screen of the navigation system, notifying the user that the address data indicating the intended destination is not found in the map database and prompting the user to determine whether to proceed for finding a partial route to the intended destination; selecting a method for inputting data indicating a tentative destination which is considered proximate to the intended destination; allowing the user to specify the tentative destination in the navigation system through the selected input method; and determining a location of the tentative destination and detecting address data indicating the location of the tentative destination for calculating the partial route to the intended destination.
