I first saw someone from a Japan website did this mod, then found a How-to from M3F.

I used the original LCD polarizer (flipped) but didn\'t like the result. The red text wasn\'t bright enough and black background wasn\'t dark enough. So I ordered a 44% linear transmittance polarizer from 3D Lens (Item #: POAT-S). Received the polarizer within a week, quick delivery

The new film gives a more black background and the red text is more visible a daytime.

Contrast of the radio LCD display set to 5 or 6.

Note: The LCD background is less red-ish in the real world.

The toughest parts were to take out the stock polarizer and to clean the glue. I used Goo-Gone and heard that the 3M Adhesive Remover is better.

Overall, I like the result

I\'ll try to snap a few daytime pix later.
