1. A navigation apparatus, comprising:

  • a memory;

    a map database, stored in the memory and configured to store data of a plurality of existed roads;

    a positioning module, configured to receive a positioning signal to acquire coordinates of a current position of the navigation apparatus;

    a comparison module, configured to determine if the coordinates are located on any one of the existed roads, and configured to determine if a shortest distance between the coordinates and any one of the existed roads exceeds a predetermined threshold when the coordinates are not located on any one of the existed roads;

    a map data adding module, configured to establish a traveling path when the coordinates are not located on any one of the existed roads, and configured to update the traveling path according to succeeding coordinates of the navigation apparatus acquired by the positioning module while the shortest distance exceeds the predetermined threshold until the navigation apparatus return to any one of the existed roads, wherein the map data adding module stores data of the traveling path in the map database as data of a new existed road only when a distance between the traveling path and the existed roads exceeds the predetermined threshold; and

    a display, configured to display a map according to data of all existed roads stored in the map database.
