Product Manual

2 If your car is a BMW, Benz, or VW brand car, you will find the
image flashing all the time after you install this system. Because
BMW, Benz, VW's cars repel foreign devices and emit interfering
currents. You need to add a relay or filter between the camera and
the lamp circuit to form a rated dc power supply.
When you turn off the engine and keep the key in ACC, if the image
does not flicker and the image starts to flicker after starting the
engine, you can be sure that you need to add relay or filter to keep
signal stable.
3 If you connect the camera to the headlights, and your headlights
are LED, it will not work. Because the LED light cannot provide a
constant direct current to the camera, you need to switch to another
power source to power the camera.
