Wow, way fancier than mine, but I went with a full digital rearview mirror 5+ years ago. It is dual layer, mirror over screen so if you change the focus of your eyes, you can still see the mirror, but otherwise it is rear view digitally. Dual inputs so I have a camera on the spoiler for straight back, and one facing down for the hitch and reverse for wheeling and trailer connecting. I love your setup!
and you can change the video to 1/4, 1/3, 1/2, 2/3 or full and orient it from either the left of right. I drive with it on, and always keep it just as shown.
It was meant as a back-up camera, so the grid doesn't work for distance with the camera pointing straight out. I mounted on the LED bar, with foam tape for vibration, and stainless steel screws into the plastic led bar.
I run it full screen all the time now, I have gotten so used to it. Added one to my other trucks as well. Need to put one in the RS, never got around to it I guess. I even have an extra screen and camera sitting in the garage...lol, laziness.
