a pedestrian mode map displaying step of displaying, when in the pedestrian mode, the map of the current location by the display unit by arranging the mark indicating the current location based on the current location detected by the current location detection unit;

receiving a setting of a plurality of destinations in the pedestrian mode;

displaying a mark indicating the plurality of destinations on the map; and

sequentially selecting respective destinations of the plurality of destinations;

setting a selected destination to be identifiable from other destinations of the plurality of destinations; and

displaying a distance to the selected destination.

8. A system for performing a display method of a navigation device, comprising:

a navigation device comprising:

a current location detection unit to detect a current location;

a current location correction unit to correct the current location detected by the current location detection unit using map matching;

a display unit to display a map;

wherein the navigation device receives a setting of a plurality of destinations in the pedestrian mode, displays a mark indicating the plurality of destinations on the map, and sequentially selects respective destinations of the plurality of destinations, sets the selected destination to be identifiable from other destinations of the plurality of destinations, and displays a distance to the selected destination;
