Get a polarization lens/filter and it will invert the colors you see.

Soon to be new car... I want to turn the center LCD in this into this.

EDIT: Actually i wonder if i can just buy the one for the Mazda 6 and swap it with the one in the 3.

Turn the polarization filter 90 degrees. You'll most likely have to get some new material, LCDs are rarely square.

Probably have to take off the current polarization filter and put a new one on. I bought a piece online a few years ago, 10 bux for a 3*5 piece. I pealed off the old one and then put the new one on and it worked like magic!

Holding one or a combo of some buttons down and getting into a hidden menu is one posibility.

There is a way to do this with the wiring that would probably be a bit difficult. It involves activating all the pixels on the screen and when it recieves input the pixles that are activated shut off.
