Now that Google Maps can give you subway, train, bus, and ferry directions in New York City, it’s a handy tool for planning a night on the town. But what if your plans change while you’re at dinner?

Luckily, Google Maps for mobile can give you the same public transit directions right on your cell phone! You can plan trips throughout the New York metro area, including turn-by-turn walking directions. With the My Location feature, most cell phones can automatically set the starting point for your trip, even without GPS. And satellite view and Street View (on selected devices) can show you a preview of where you’re going.
