(2008) Service Advisory 0851 Rev A: GMX 200 Display Color Shift
AFFECTED PRODUCTS
All GMX200 Series Units
DESCRIPTION
Garmin has identified an issue with the operation of GMX 200 Units:
When the display backlighting is set to the maximum level and the GMX 200 is operating in high temperatures there may be a noticeable color shift to some of the colors displayed on the unit. If a change in colors does occur, reducing the backlight intensity will resolve the issue.
RESOLUTION
To reduce the backlight intensity, press down on the “-” side of the power rocker switch located on the upper right of the unit, until the color shift is no longer apparent.
Garmin and the FAA have concurred that this does not affect safety of flight. This condition will be corrected in upcoming display board software that will require the unit to be returned to the factory for installation and color calibration.
