Abstract
A navigation device includes a receiving unit, a positioning unit, a memory, a orientation detector, a processor, and a display. The receiving unit is used for receiving positioning signals. The positioning unit computes current positioning information of the navigation device according to the positioning signals. The memory is used for storing an electronic map. The orientation detector is used for detecting a turned angle and a turned direction of the navigation device. The processor is used for obtaining the electronic map from the memory and rotating the electronic map according to the turned angle and the turned direction. The display unit is used for displaying the rotated electronic map and the current positioning information of the navigation device on the rotated electronic map.
