TeleNav - $9.99/mo

TeleNav is a mobile GPS navigator now available for the Android G1 phone. TeleNav provides on-the-road access to full-color, 3D, turn-by-turn GPS navigation along with advanced speech recognition; traffic alerts with one-click rerouting; more than 10 million business listings; gas prices; weather updates and restaurant reviews.

The menus seem straight forward, however when I tried the speech recognition to get directions to a location, it did not work very well. I ended up typing the address. The traffic feature is nice and gave detailed information on road hazards and traffic accidents. One last thing that was important was GPS Satellite reception, which was not up to par with most GPS navigators. It continuously kept losing the signal even when it was clear, which made navigating a nightmare. There was also a considerable delay of the GPS audible turn by turn directions making navigating very difficult, even when my vehicle was moving at only 30 mph.

A one month trial is available, after which the $9.99 per month charge kicks in.
