Touch Panel Check 1
WARNING: This page is about a different car, the 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. 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 displays the coordinate of the location, and a + icon appears where you touched the screen. If any areas of the screen either don't respond, or respond at some other location when touched, then replace the audio-navigation unit.
NOTE:
Unlike earlier screens that used infrared sensors, direct sunlight does not affect this test.
