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 inMexico 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.
