Japan's safety guideline on in-vehicle display systems.

Japan Automobile Manufacturers Association, Inc. (JAMA) drew up the safety guideline on in-vehicle display systems, which is targeted mainly at car navigation systems, and put it into effect in Japan in November 1990. This guideline applies to the display systems installed in vehicles at the factories of Japan's 11 vehicle manufacturers and to onboard VICS (Vehicle Information and Communication System) equipment, including after-market products. To date, approximately 500,000 vehicles fitted with such equipment have been sold in Japan. This paper describes the background behind the formulation of this guideline and the basic concepts and details embodied in it.
