Today, I went to change the brightness of my camera screen and found out it won't let me. The contrast control works, but the buttons + and - are just back shaded in blue for the brightness....So then I went to the audio screen and tried to change it in the menu from there...still can't change it. This seems wierd to me...I couldn't find any other controls, like for sound or other areas that did not work...only the screen brightness control. Anyone have this before? I'd hate to have to have the whole navigation unit pulled just to fix this problem. Hopefully it can be reset or rewired....who knows! :banghead: Thoughts appreciated!
