Did you think you needed to buy an expensive GPS-enabled phone or PDA? Think again! The Telenav GPS is a service that gives you even more features besides turn-by-turn driving directions. It has a business finder, traffic finder and rerouting. It also has full color maps, voice directions and much more, all on a regular cellular phone! I should have known earlier before buying a Bluetooth GPS Receiver!
Implications - You can use the TeleNav system whether you are driving in a car or walking by foot. You can take it anywhere you want since it is installed right to your cell phone. You won't ever have to worry about being lost again!
