Gentex Mirror-Based Backup Camera Display Featured on 2010 Toyota SUV and Pick-Up

ZEELAND, MI, Jun 24 (MARKET WIRE) --
Gentex Corporation (NASDAQ: GNTX), the leading supplier of
automatic-dimming rearview mirrors to the worldwide automotive industry,
has announced that it is shipping auto-dimming rearview mirrors with its
Rear Camera Display (RCD) feature that will be available on the 2010
Toyota Tundra and Sequoia. The Tundra is sold in North America and the
Sequoia is available in North America and Gulf Coast countries including
Saudi Arabia and Qatar.

The Gentex RCD Mirror is offered as optional equipment on all Tundra trim
levels and is standard on the Limited Sequoia trim level. In addition, the
Tundra and Sequoia continue to offer Gentex interior auto-dimming mirrors
with features including compass which utilizes Gentex's proprietary
Z-Nav(R) technology, a highly-accurate sensor that determines the
vehicle's directional heading, and a universal garage door opener. Both
vehicles also offer exterior auto-dimming mirrors with turn signal
indicators on various trim levels.

The RCD Mirror contains a liquid crystal display (LCD) 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 display appears automatically through the auto-dimming
mirror's reflective surface. The display disappears when the vehicle is
shifted into any other gear, a capability that is made possible utilizing
Gentex's "transflective" coating and lighting techniques, which result in
a bright, high-resolution color image.

"Rear view camera displays continue to gain in popularity and we're
excited to be working with Toyota in offering this feature for two
additional vehicle models," said Gentex Senior Vice President Enoch Jen.
"The mirror is an ideal and intuitive location to display rear camera
video because it allows the driver to view the display and the reflected
scene simultaneously."

Founded in 1974, Gentex Corporation 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.
