A navigation method includes steps of: repeatedly emitting, by a wheel speed sensor (3), a pulse signal to a processor (5) of a vehicle (1) when the vehicle (1) starts to travel from a start point of a route of a map; in response to receipt of a preset number of the pulse signals transmitting, by the processor (5), the preset number of the pulse signals to a portable device (6) ; calculating, by the portable device (6), a current position of the vehicle (1) on the map based on a distance associated with the preset number of the pulse signals; and transmitting, by the portable device (6), data of the map having the current position to the processor (5) so as to display the same.
