How does this system work?
This system come with regular GPS navigation function, Bluetooth function, media player function and AV input function. Among those functions, Bluetooth function is set as first priority, and AV input function is set as second priority. When the camera signal is received, the device will switch to camera mode automatically, after signal is off, it will auto switch back to previous screen.
 

Camera
This CCD Color camera is a wide range voltage input (DC 12?32V) designed for all kinds of vehicles. It is a waterproof alloyed shell camera, with 18 LED lights for Infra Red night vision.
The Universal Mounting Bracket is adjustable, therefore suitable to install anywhere. The camera can be connected to always-on power or switch-activated power (like backup lights power, left/right turn signal lights power).
