Navigation image display method

The invention discloses a navigation image display method. The navigation image display method includes steps of A, a CPU unit of a navigation device calculates current position where the navigation device locates according to the GPS signal of a GPS receiver of the navigation device, and calculates the guidance path from current position to the destination according to the destination information input by the touch screen operation unit of the navigation device; B, if the navigation device carrier starts to move along the guidance path, and the navigation device starts the navigation in real time; C, the CPU unit calculates the movement line of the navigation device carrier from current moment to the next second by referring to the guidance path. The method can accurately locate the navigation image position in real time, realize the accurate navigation; the method can realize relatively accurate navigation even when GPS signal cannot be acquired within a short time.
