the universal kit you referenced is not a perfect world on display either, it is not a projection system

you need to place the box on top of your windshield and then affix a reflective window tint square onto your window

in other words all it is doing is displaying a reverse image that the mirro on the inside of your window is aimed at

here is a pic that explains what I mean, you can see how the large square is on the windshield at all times

you may see it but not very clearly during the day plus you would still have that ugly box sitting on top of your dash

in my opinion not worth $200+ but it's your wallet, not mine
