MRX920 unit to make it easier and more comfortable to use.
Contrast
The laptop XGA display is a transmissive color display designed to
minimize glare and maximize transmitted light from the backlight
so it has excellent readability in indirect light. The XGA display is
easy to read in vehicles. However, to increase or decrease the
brightness of the display, perform one of the following actions.
• Press
FN + F6 to decrease LCD brightness.
• Press
FN + F7 to increase LCD brightness.
If the route data file is not found, a message displays. See “If No Route Data File is
Found.” on page C-5, for instructions.
