Heads up display question, please help
I have a 2000 coupe and the windshield is cracked. I have HUD and they are telling me I have to have a special windshield for the HUD. It's like 850 dollars. Is that right or can I get away with a regular windshield?

I had hud on my grand prix and before it went back (off lease) I put a regular windshield in it and really couldn't see much difference in the hud info. it was a bit less bright but that is about all.
hope that helps, someone who has done this will chime in.

There is a reason for the special windshield but most people can't really see the difference anyway. There is a special coating between the 2 panes of glass to keep the HUD image in focus. When projected at the windshield, there will be 2 images, one on the inside and one on the outside a NORMAL windshield, HUD glass has the coating in betwwen where the image actually focuses so you see no distortion. Your eyes (and mileage) may vary.

There have been a number of people that have either added a HUD to a car with a regular windshield or have replaced a HUD windshield with one that is on a non-HUD car - and in each case the owner reports that the HUD can be seen just fine.

Obviously a standard windshield works OK but the HUD windshield will give you optimal performance. A couple of owners who installed standard windshields did comment on poor HUD reflectance/performance in certain situations but it wasn't a show-stopper. I would opt for the HUD glass if insurance is footing the bill. $850 is actually only half what those traditionally go for. If you do get a Hud windshield, make sure you check for the proper label to ensure you are indeed getting the real McCoy.

BTW: it works great even with the top down.

If you go the insurance rout the deductible is the same so go for the HUD glass unless you are hoping to find one less than that amount!Try going online (Corvette Recyclers for example,,and you might find a HUD wind shield at a good price,, I'm sure there are other salvage places too!!

I've installed HUD on a non HUD car with regular windshield, no issues and definitely no double images. From what I remember the only difference was the thickness of bonding material between two panes of glass. HUD being thiner. I'm not 100% positive but I think they don't even differentiate between the two in C6 line. Again if the insurance is funding the replacement go with HUD windshield, if not don't waste your money.

You got some good advice here. The HUD windshield is different and, as the guys say,its to do with the different lamination and treatments to get the best reflectivity.
If I were you I'd soak up the deductible and get the OEM HUD windshield that costs way more than that. That way you know you won't have reflection/double image issues.

It's not just about double images, it's also about seeing THROUGH the image. The theory of the system is out there, GOOGLE it. There's a reason the windshield is built that way, if the image is OK for your eyes-go for it. ABout 1/3 of the way down this doc explains it:
