Press Release Summary: TeleNav GPS Navigator(tm) now available through Nextel Mexico
and Nextel Brazil

Press Release Body: Sunnyvale, Calif. and Reston, VA - November 15, 2007 - TeleNav,
Inc., the first company to launch a GPS navigation service for mobile phones in the
U.S., and NII Holdings, Inc. [NASDAQ: NIHD] today announced that getting around in
Mexico and Brazil just got easier with the launch of TeleNav GPS Navigator(tm).
Nextel Brazil and Nextel Mexico customers in selected cities now have access to
turn-by-turn, GPS-enabled driving directions on both the Nextel BlackBerry(r) 7100i
and the Nextel BlackBerry 7520 mobile handsets.

\"The need for reliable driving directions is global,\" said HP Jin, president, CEO
and co-founder of TeleNav. \"The benefits of cell phone GPS systems over traditional
navigation systems or printed maps are relevant in any country. TeleNav\'s products
are popular in North America, Europe and Asia, so it\'s a natural progression for us
to continue to expand further within Latin America.\"

TeleNav GPS Navigator provides voice and onscreen turn-by-turn directions, just like
car navigation systems and personal navigation devices (PNDs), but at a fraction of
the cost. For as little as $140 pesos per month (Mexico) and $15 reais per month
(Brazil) for unlimited use, Nextel Mexico and Nextel Brazil wireless customers can
use TeleNav GPS Navigator in any vehicle or while walking. Voice directions are
available in Spanish, Portuguese, and English. While driving, users get up-to-the
minute guidance, including street names, and will automatically be re-routed if a
turn is missed. The service also includes access to business listings so customers
can look up addresses and get directions directly from their Nextel BlackBerry
handsets. Maps and business listings are updated automatically and at no additional
charge.


\"Cell phone GPS systems are a natural solution for customers who travel often for
both business and personal reasons,\" said Greg Santoro, NII\'s chief strategy and
marketing officer. \"TeleNav GPS Navigator is by far the most feature-rich and
compelling navigation application available today.\"

Both Nextel Brazil and Nextel Mexico are currently offering a free 30-day trial of
TeleNav GPS Navigator.

Features of TeleNav GPS Navigator for Nextel Brazil and Nextel Mexico customers
include:

* Voice and on-screen turn-by-turn driving directions - Customers enter in
destinations and TeleNav GPS Navigator computes the routes. While driving, users get
up-to-the minute guidance, including street names, and will automatically be
re-routed if a turn is missed. Directions are available in Spanish, Portuguese, and
English.

information or having to pay for updates. TeleNav provides this to its customers
automatically and at no additional charge.

including banks, restaurants and hotels, and easily navigate to them with the click
of a button.

* Pedestrian Mode -TeleNav GPS Navigator can also be used while walking, to help
