This diagnostic screen checks for pixels that may be
stuck on. The entire display must be black. If pixels are
stuck on, replace the navigation unit.
The panel touch sensing system consists of a touch
sensitive resistive membrane covering the display.
Contrary to other systems using infrared beams, the
screen has to be physically touched to make it work.
The display has the capability of 479 touch locations
(left to right), and 233 touch locations (top to bottom).
The upper left hand corner is position (0, 0) and the
lower right hand corner is (479, 233) as displayed.
Touching anywhere on the screen displays the
coordinate of the location, and a icon appears where
you touched the screen. If any area of the screen either
doesn’t respond, or responds at some other location
when touched, then replace the navigation unit.
NOTE: Unlike earlier screens that used infrared sensors,
direct sunlight does not affect this test. The display screen uses a touch sensitive membrane.
This means that every location of the entire surface of
the display is touch sensitive. This diagnostic allows
alignment of these touch locations with the location of
the buttons images on the screen.
Normally this should n
ever need adjustment, and is
used only to adjust the touch locations for parallax (the
touch locations appear different when viewed at an
angle). However, if an adjustment is necessary, follow
this procedure:
The screen consists of the button icons. Touch the center of the five buttons on order 1 5.
To store any change you make, touch the Set button.
Use the Return key to exit the diagnostic.
