OnStar Extends Service with Airbiquity

Today, Airbiquity Inc announced an extension of its service with
OnStar, the nation's leading provider of in-vehicle safety, security
and communication services. Airbiquity, a leading developer of
wireless in-band modem software solutions for automobile manufacturers
and suppliers, will continue to provide OnStar with its aqLink
software, which facilitates the exchange of vital information with
drivers nationwide.

"Airbiquity has become a trusted supplier and fills a key role in
providing OnStar with dependable, effective technology solutions,"
said Nick Pudar, Vice President Planning and Business Development for
OnStar.

After extensive testing with competitive technology providers,
OnStar again chose to integrate Airbiquity's unique approach to
over-the-air data transfer into its popular in-vehicle communication
devices. Since 2003, Airbiquity's aqLink software has made it possible
for OnStar subscribers to utilize digital wireless voice channels to
receive real-time location-based services, which now include roadside
assistance, vehicle diagnostics, turn-by-turn navigation, airbag
notification, remote door unlock, stolen vehicle location and much
more. By employing voice networks rather than relying on conventional
wireless data systems for safety and security applications, aqLink
expands OnStar's coverage area and makes data transmission more cost
effective.

"The extension of our relationship with OnStar will allow
subscribers to continue receiving exceptional data communications
while providing OnStar with the means to expand current offerings to
subscribers," said Kamyar Moinzadeh, president and CEO for Airbiquity.
"This renewal of our relationship demonstrates that OnStar continues
to consider Airbiquity among its trusted technology providers."
