ZEELAND, MI -- (MARKET WIRE) -- May 23, 2007 -- Gentex Corporation (NASDAQ: GNTX), the leading supplier of automatic-dimming mirrors to the worldwide automotive industry, has announced that it is shipping interior auto-dimming mirrors for the 2007 Jeep Patriot. The Patriot is a compact SUV being sold in North America and other select markets.

Gentex auto-dimming 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.

An auto-dimming base interior mirror is available as part of a "Driver Convenience Group" on the 2007 model year Patriot Limited trim level or with an optional UConnect® Hands-Free Communication system integrated in the Gentex interior mirror. The Sport E trim level offers the same auto-dimming mirror as part of an optional package.

"The Patriot is expected to attract a new group of vehicle buyers to the Jeep brand," said Gentex Senior Vice President, Enoch Jen. "Gentex is excited that Jeep is including our glare elimination and microphone technologies in their expanding product line."

Founded in 1974, Gentex Corporation (NASDAQ: GNTX) is an international company that provides high-quality products to the worldwide automotive industry and North American fire protection market. Based in Zeeland, Michigan, the Company develops, manufactures and markets interior and exterior automatic-dimming automotive rearview mirrors that utilize proprietary electrochromic technology to dim in proportion to the amount of headlight glare from trailing vehicle headlamps. Many of the mirrors are sold with advanced electronic features, and approximately 96 percent of the Company's revenues are derived from the sales of auto-dimming mirrors to nearly every major automaker in the world.
