Abstract
A method for providing a geo-fence service using a map provided via a navigation device includes: searching for at least one critical route from a current position of a vehicle or an origin to a destination mapped onto the map; displaying a first critical route onto the map along the vehicle can travel to the destination, the first critical route corresponding to a shortest route among the at least one searched critical route; and determining whether the vehicle deviates from a geo-fence area including the at least one searched critical route.
