In honor of the summer travel season:
Problem: You're lost, you don't have a map and you need directions.
Solution: Use your cell phone to get directions by text message. There are several free services that will send you directions, and you don't need a smart phone like a BlackBerry or an iPhone.
To use Google's service, send a text to 466-453. (It spells "Google.") In the body of the text, include your starting location followed by your destination (for example Second St. and Third Ave. NY NY to 45th St. and 8th Ave. NY NY). You will then receive multiple text messages with driving directions to your destination. The number of texts that you will receive depends on how many steps are included in the directions.
If you are already behind the wheel, avoid texting and call (347) 328-4667. (It spells "directions.") With this program, you tell an automated service where you are and where your destination is.
After this, you'll get several text messages with your directions. Although these services are free, you might incur charges under your cell phone plan.
