September 13, 2004... ZEELAND, Michigan USA -- Gentex Corporation (Nasdaq: GNTX), the leading supplier of automatic-dimming mirrors to the worldwide automotive industry, is shipping automatic-dimming mirrors for the 2004 BMW 5 Series, 6 Series convertible and coupe, and the X3 Sports Activity Vehicle. ADVERTISEMENT Gentex mirrors automatically darken to reduce glare from the headlamps of vehicles approaching from the rear. The brighter the glare, the darker the mirrors become, making nighttime driving safer. The new 5 Series offers interior and exterior auto-dimming mirrors in a popular option package. A Gentex three-mirror, auto-dimming system comes optional on the 6 Series, and the base interior mirror can be upgraded to include Johnson Controls HomeLink? Wireless Control System. Three buttons conveniently located on the face of the mirror can be programmed to operate garage doors, estate gates, security systems, home lighting, and other radio frequency-controlled devices. The all-new X3 offers a base interior auto-dimming mirror as part of an option package, with HomeLink as an additional upgrade to the mirror. Gentex mirrors have been a fixture on various BMW models for many years, and these new mirror programs illustrate our continued, growing relationship with the manufacturer. Its especially exciting to be a part of the new X3 model, because sports-activity and crossover vehicles are increasing in popularity, said Gentex Executive Vice President Garth Deur.
