I am doing a Navi conversion to my CL and ran into a little problem. I seems that the Display a/c button does not work. I did a search on in the TL section and it turns out it has happened once before to "kuzdu" but there were no answers. The system i have is from a 2000 TL. I know i did the wiring right becuse i borrowed a spare screen from a friend and it works just fine but when i plug my screen in the same problem.

Anyone know why or had any similar problems. i opened the screen to check and see if the button was getting contact and it was fine. Any advice besides "go buy a new one" let me know. Thanks. Pics of inside display below.
