Abstract
A navigation apparatus and a method for updating map data thereof are provided. A map database of the navigation apparatus stores data of a plurality of existed roads. When coordinates of the navigation apparatus are not located on any one of the existed roads, a comparison module of the navigation apparatus determines whether the shortest distance between the coordinates and the existed roads exceeds a predetermined threshold. If the shortest distance exceeds the predetermined threshold, a map data adding module updates a traveling path according to a plurality of succeeding coordinates of the navigation apparatus until the navigation apparatus is determined to return on one of the existed roads. When the map data adding module finishes updating the traveling path, the map data adding module stores data of the traveling path in the map database of the navigation apparatus.
