System Description

  1. ELECTRO MULTI-VISION SYSTEM OUTLINE 
    1. The electro multi-vision system is provided on vehicles without the electro multi vision system. This system, as with vehicles with the electro multi vision system, provides a touch screen interface for the user to view vehicle information, operate systems such as the air conditioning system and change various settings.
  2. TOUCH SCREEN OUTLINE 
    1. Touch switches are touch-sensitive (interactive) switches operated by touching the screen. When a switch is pressed, the outer glass bends to contact the inner glass at the pressed position. By doing this, the voltage ratio is measured and the pressed position is detected.
