Lense is clean. How can I increase brightness? Yah, I turned up the dash dial. Does a GTP with HUD need a special windshield? Mine is cracked, thanks to a tanker on the hwy. The cracked has spread in 2 days half way down windshield

See earlier post about a cold solder joint. As for the windshield yes it's "special" turn it in to your insurance they run about $900 US. Some people have gotten away using a standard WS but more have had degraded HUD clarity from minor annoyance to un-readable.

Wow, tks for the news! I'll pay. It's worth it
