Abstract
In a navigation method for tracking a second electronic device using a first electronic device, the first electronic device receives position information of the second electronic device. A position of the second electronic device is marked on a navigation map stored in the first electronic device. The first electronic device is directed to track the second electronic device according to the marked position on the navigation map.
