What did you do to your GS today?

Not exactly today, but recently. Swapped in my SD black wood from the wrecked car, it helps the tan interior considerably. Also received some more polarizing film, so I took my climate control panel apart and inverted the LCD to match what I had previously done to the radio, then swapped the backlighting for white LEDs.

The basics are fairly simple; a liquid crystal display works by changing the polarization of light passing through two polarizers, one before the "liquid crystal" and one after. In stock configuration, they are parallel, so the backlight passes through and the light is polarized perpendicular to the front polarizer where the symbols are, making them appear black. By changing (or "inverting") the front polarizer to be oriented perpendicular to the rear one, no light gets through except where its polarization is rotated by the "liquid crystal" causing the characters to light up.
The process of actually doing it is a little scary, as it involves disassembling the climate control panel and (ideally) removing the display from the board (desoldering) for easier access. One then carefully peels the original polarizer off of the front of the glass using a razor blade and a heat gun to soften the adhesive. The rest of the adhesive is removed from the glass with adhesive remover. The new polarizing film is then oriented over the glass so that is appears black, trimmed to fit, and stuck on. Everything goes back together and you're done. I'd post some pictures, but I neglected to take any during the procedure. The radio is easier to do, as the display is attached to its own little circuit board that is a little easier to remove.
