Special windshield for HUD ???
 

The GM manual says that you have to make sure you get a special windshield that will work with the HUD.

Someone else told me this is a very expensive windshield. Does anyone have any info on this?

Yes, it's got a special coating that prevents your seeing a double reflection of the display.

That wouldn't surprise me; they frequently get broken when the airbags deploy (especially by the passenger's side bag, where the lid flips up and breaks the glass), so used junkyard ones may be hard to find.

I assume you need a replacement; would your insurance cover it?

Here is some more info, probrably a repeat though.

FWIW, I retrofitted a HUD into our 97 Grand Prix--it has the "non-HUD" windshield, and it works just fine--no double displays, can still be read in daylight.

I've seen a couple theories online--one says that the HUD windshields have a special coating, the other says that they have gone thru a higher quality check that ensures there are no "ripples" in the glass in the area the HUD is displayed on--I have no idea which one is correct

I heard that you can get a special "filter" or "screen" that you stick onto a normal windshield that helps the HUD image... instead of forking out the money for a real HUD windshield. But again, I don't know the difference between a non-HUD and HUD windshield, but both times I had mine replaced, the glass repair shop always goes out of their way to phone me and ask if I have a HUD or not.

I don't know why he asked unless he didn't know from 88-91 HUD wasn't on the Bonneville yet.

They see all the other cool features on the car like the compass and the DIC and they figure it must have a HUD.... hehe. Also.. anything that goes that fast should have a HUD ;)
