Read this explanation:
"One thing that has already been eliminated from consideration is integrating the video screen directly into the mirror via a through-the-glass display. Magna’s engineers say they have tested such a system and compromises in image clarity, along with human interface issues, virtually eliminate that option. As the human eye matures it has difficulty focusing on different focal lengths so when you focus your eyes on a mirror that has a focal distance of infinity and then on a display that has a focal point from your eyes to the screen, your brain struggles at which to look at."

That quote is funny.
The focal length to their screen is a whole 1 mm different from an Audiovox in-the-mirror screen (the thickness of the glass), so they have the same difference in focal length between the reflection in the mirror and the image on the screen!
If you have not yet purchased a camera and screen, there are some other options,
particularly for handy people like you.
I bought a microminiature CCD camera to place in the top of the tailgate. The field of view is such that you can see corner to corner on the bumper as well as the hitch.
I got a separate LCD to fabricate into the sunglass holder (although it could go anywhere.) Only thing is it will require some custom fabbing. Right now I am thinking of having an actuator open and close the sunglass holder with the screen inside whenever the truck is in reverse (with a delay to leave it open for a minute or so for back and forth situations).
The total cost should by much lower than the system you linked, and marginally less than the OEM system.
I don't mean to hijack your thread, I just wanted to float another option in case you hadn't yet made the investment.
