Touch Panel Calibration

The display screen uses a touch sensitive membrane instead of fixed infrared "beams". This means that every location of the entire surface of the display is touch sensitive.

For the display to be compatible with earlier navi systems, the system software creates "touch zones" emulating the touch "switches" created by the intersections of 20 vertical and 10 horizontal infrared beams. This diagnostic allows alignment of these artificially created "zones" with the location of the button images on the screen.

Normally this should never need adjustment, and it 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 four test areas consisting of a "+" button and an adjacent box with a black border. Touch the four "+" buttons to verify alignment. If, when you touch a "+" button, the adjacent box becomes yellow, then do the following. Continue to hold the "+" button, and simultaneously move the joystick to shift the screen slightly from side to side, or up and down. The adjustment is complete when you can touch all four "+" boxes and none of the adjacent boxes becomes yellow.
• To store any changes you make, push in the joystick.
• To reset the touch zones to the factory default, touch the Map/Guide button.
• Press Return to exit the diagnostic.
