Method for adjusting displayed navigation direction using sensors and navigation device using the same
A method for adjusting displayed map using sensors is disclosed, applied in a navigation device. The method includes steps of: calculating a GPS-based rotating angle of the navigation device based on location information detected by a GPS module of the navigation device when a coordinate error value of the navigation device is less than a predetermined value; using a sensor of the navigation device to detect the sensor-based rotating angle of the navigation device when the coordinate error value of the navigation device is greater than the predetermined value; rotating a map on the screen according to one of the GPS-based rotating angle and the sensor-based rotating angle depending on the coordinate error value.
