Gentex Mirror-Based Backup Camera Display on First New Korean Model

ZEELAND, MI--(Marketwire - December 20, 2007) - Gentex Corporation (NASDAQ: GNTX), the leading supplier of automatic-dimming rearview mirrors to the worldwide automotive industry, has announced that its rear camera display mirror will be available for the first time in the Korean market on the all new Kia Mohave available in early 2008. The Mohave is the first mid-size sport utility vehicle from Kia. It will be sold in North America as the Borrego and will be available beginning in mid-2008.

An interior auto-dimming mirror with rear camera display will be available on the Mojave models sold in the Korean domestic market. The North American version of the vehicle will offer an interior auto-dimming mirror with either HomeLink® or HomeLink® with a compass display. HomeLink® is Johnson Control's fully integrated wireless control system.

Auto-dimming mirrors darken automatically to eliminate glare from the headlamps of vehicles approaching from the rear for improved nighttime driving. The Gentex auto-dimming interior mirror also contains an LCD display that works with a video camera mounted at the rear of the vehicle to provide a view directly behind the vehicle while backing up. When the vehicle is shifted into "reverse," a 3.5-inch diagonal LCD display appears automatically through the auto-dimming mirror's reflective surface. The display disappears when the vehicle is shifted into any other gear. The unique capability for the display to appear through the mirror's surface is made possible by Gentex's proprietary "transflective" coating and lighting techniques, which result in a bright, high-resolution color image.

"Gentex's rear camera display mirror technology is easy to integrate into the vehicle and no longer needs to be tied to an expensive navigation system," said Enoch Jen, Gentex senior vice president. "The rearview mirror is a cost-effective way of providing this new safety-assist feature on a wide variety of vehicles. We are pleased that Kia Motor Company chose Gentex to introduce this feature in Korea."

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 more than 96 percent of the Company's revenues are derived from the sale of auto-dimming mirrors to nearly every major automaker in the world.
