Got some news about the windshield display properties today, specifically for the Cadillac but it might be useful for other cars.
Had a chat with a guy who was part of the NV design/implementation team for GM about 7 years ago, right around the time they were installing the NV cameras hot and heavy.
Basically, the factory stopped making "special" windshields for the Deville in 2001, and went a different route altogether. They actually tested batches of completed windshields from their suppliers at the factory. The ones with a higher reflectiveness were reserved for cars ordered with NV, and the ones with a low reflectiveness and leftover high reflectiveness went into the cars ordered without.
The difference was about 1-1.5%, not much, and well within tolerance. Standard glass reflects about 3.0% per surface, the ones that were considered "high" were 4.5%+ per surface. It saved them ****loads of money, and did the job of displaying the HUD infor just as well.
The reason I bring this up is for you guys playing with the nitemax and such, you may not need to get all involved with filters and tints, YOUR glass may do the trick all by itself. At least give it a shot first...
Also, if you have a few grand burning a hole in your pocket, there are 2 auctions running right now for the Caddy NV setups.
