A GPS navigation device with a car rear-viewing function is disclosed herein, which includes a monitor, a GPS navigation module receiving a GPS navigation information and providing it to the monitor, a car rear-viewing module providing a car rear image from a camera to the monitor, a switch unit, and a micro control unit. When the shift lever of the car is located in a reverse gear position, the micro control unit sends a switch command to the switch unit to allow the car rear-viewing module to transmit the car rear image to the monitor. In contrast, when the shift lever is not located in the reverse gear position, the monitor is switched to be controlled by the GPS navigation module for displaying the navigation information. Therefore, there is no need to install an additional monitor for displaying the GPS navigation information and the car rear image information, respectively.
