Touch Panel Check
WARNING: This page is about a different car, the 2008 Acura CSX, 2007 Acura CSX, and 2006 Acura CSX. However, it is still accessible from the selected car via links, so may be relevant.
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 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 will display the "coordinate" of the location, and cause the place you touch to display a "{" icon. If any areas of the screen either don't respond, or respond at some other location when touched, then replace the navigation unit.
NOTE:
Unlike earlier screens that used infrared sensors, direct sunlight will not affect this test.
