Input:
Question: I cannot get the display to automatically turn off after the transmission is switched from reverse to drive or after the truck is turned on.
Document: The mirror itself when the display is off is ok, has a sorta dark green tint to it, so if you have limo tint rear windows I'd think long and hard about it. True you can look in your rear mirror display when you're reversing, but at night driving down the road I don't think you'd be able to make much out in the mirror.So the good news, the mirror works fine when it's working, just hope you get a good one.
Not really any installation instructions included, but all the wire leads are labeled so with a little basic understanding of 12 volt automotive wiring, there weren't any problems. It did have a page on making adjustments to the display settings though.The video cable from the camera to the mirror was long enough for the installation on my full size truck, but I did have to extend the power lead wires from the camera to the front fuse box area.
works great, good image. Instructions not super clear, but i tested and figued out the configuration before i stared the install. If you wire the camera power and the mirror's wire labeled 'backup lights' to the hot on the reverse lights and plug the video into input 2, the camera/screen come on automatically when you shift into reverse. i likethe keyhole factory look of the camera.
The mirror is optically not perfect (slight distortion) and has a green tint to it which makes everything darker than normal although neither is a deal breaker, including at night. I used the included mirror mount rather than just clipping the display mirror over the existing mirror, but it's adjustment angle isn't quite as wide as the original mirror bracket.
I like the system very much. It does make me feel much safer backing up. The only problem I have noticed is sometimes there seems to be quite a glare on the monitor part of the mirror.We had it installed and. Didn't get any instructions so don't know what. The buttons and arrows the mirror do
Wide, clear camera view and not too difficult to install. The camera goes on as soon as I put the car in reverse.
We also had to drill a hole in the floor of the truck. There is a kit with the mirror with a gasket, hole saw, etc to help you with drilling through the floor (if you need to).I saw another review that dogged the camera so I went ahead and bought a separate camera that attaches to the license plate and has night vision with built in LEDs.
The mirror should be wired to the reverse lights 12v+, I tried it as an accessory 12v+ and it wasn't what I had in mind. You CAN manually switch the mirror on even when not in reverse, but it will ONLY show cams that are powered up (hence the different wire sources for front and rear cams.)
I bought this after I backed into a parked motorcycle in my truck. After an afternoon of tinkering with some help from a friend who is an auto mechanic I was able to use this with zero further adjustments (in other words, once I got it working right I didn't have to touch it).1. The camera that comes with ita. DOES have the picture reversedb. Has a built in trapezoidc. DOES have correct color sensed. Does NOT seem to have night vision.2.
Like others, I was a little confused with some of the installation instructions, but with a little trial and error, I was able to get it up and running.Likes: Option for full mirror replacement or snap-on, good quality, good image from both monitor and camera, lines from cameraDislikes: Mirror has coating that makes vision darker, plastic mirror has a little distortion, instructions are confusing, would have liked an ability to angle the camera with a keyhole flush mount.
Answer: typically at the fuse box it is just power and it is switched later.  you could test where you are tapped to see if it is turning off when it's not in reverse
