A method and apparatus for a navigation system displays a route guidance list that lists information on roads that intersect with a calculated route to the destination in an organized and simplified manner. The method includes the steps of calculating a route to a destination specified by a user, retrieving information on intersecting roads that intersect with the calculated route; and displaying a route guidance list which lists road names on which the calculated route is established and a distance associated with the intersecting road. The route guidance list shows one integrated road name if there are two or more identical road names consecutively on the calculated route and an overall distance of the identical road names that intersect with the calculated route.
