At least on the NAV Unit..
"I have noticed several people mention their radio display was set in the Negative Mode (Dark Background/Light Numbers & Letters). This is an adjustable function. The Navigation User's Manual, page 99, under Display Settings will let you set the mode to Positive, Negative and Automatic (controlled by the headlight switch). I have the auto mode set. This gives you the light background/dark numbers during the day and switches to the dark background/light numbers at night when the headlights are turned on.
To select a setting, request the user menu and press the
LCD multifunction key to select the negative, positive, or automatic mode."
