We integrate into the factory backup camera for this 2010 Mazda CX-9!
This 2010 Mazda CX-9 contacted us after installing his new Sony radio. He was looking to have us integrate is OEM backup camera to the new radio.
The factory radio in these Mazda's internally provides 6-volt power to the camera, and when removing and replacing you have to create a new 6-volt source for the camera to operate. We accomplished this with an AX-CAM6V. Once you have powered the original camera you need to solder on and RCA to the video signal wiring and you are set!
