TeleNav GPS Navigator includes listings of more than 10 million businesses and services, including restaurants, hotels, shopping malls and banks – providing users access to restaurant ratings and reviews as well as phone numbers for business listings.

The service also includes frequently updated gas price listings so drivers can look for the cheapest gas in their area or along their route.
