1. A method for adjusting displayed map using sensors, applied in a navigation device, comprising the 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.
