I can't seem to find the brightness controls to control how bright the screen is. I have the illumination wire hooked up, and the nav dims at night when the lights are turned on, but during the day, I have probs seeing the radio/cd screen because of the darkness. I have looked through all the settings and can't seem to find it. Thanks.

Hold down [V. Adjust] button on the face for a couple seconds and the turn up the dimmer

Thanks!
