I have this installed. Instructions lack certain key things not mentioned hook pos wire to blue rem amp power wire and black to neg. Reverse auto comes great but give camera time to power up before putting car in reverse. Tiny click button is a reset on off switch. If camera view wont come on just turn off click button then turn stereo back on camera will be back on. Can be wired direct to battery but that would drain it fast with camera always on. Remote stereo wire powers camera perfect. There are lots of adjustment features from stereo to camera compatible with each other. Excellent picture quality and color for tiny lens.
