  • a storage unit configured to store map data;

    a display unit configured to display the map data and a route from a current location to a destination on the map data;

    an image capturing unit for capturing an image of a road; and

    a controller configured to receive the captured image and determine therefrom whether or not the transportation device is on an unmapped road based on an indication that the transportation device is on a road not reflected in the map data, to obtain unmapped road information and road guidance information for the unmapped road based on the determination result, and to store the unmapped road information and the road guidance information for the unmapped road as part of the map data, to check the number of times that the transportation device gets off of the route, to store locus information when the transportation device gets off the route, and when the number of times that the transportation device gets off of the route is larger than a pre-set number, the controller gives a weight value to the link or links corresponding to the locus information, wherein the weight value is a value for setting the locus information as a preferred route.
