I read somewhere that the windsheild is different. It was in a forum post on some website that listed the problem of "blurry HUD" as being a problem of having a stock non HUD windsheild being installed on a HUD equipped Grand Prix. The post basically said some people were experiencing blurry HUDs due to non HUD windshields being installed on Grand Prixs at the factory due to a Pontiac mishap on the assembly line.
So does this mean we would also have to replace our windshields with HUD windshields or is this just wrong?
