I have a 2004 Pontiac Grand Prix GTP with Heads Up Display. My windshield is broken and needs replaced. I've called several body shops and mechanics to ask about getting a new one. Some tell me that because of the HUD it has to have a special windshield, but others tell me it doesn't. I can't tell if they're trying to rip me off for a more expensive replacement, or if I'll get the cheaper one and the HUD won't reflect off of it. HELP?!?!?!
