Now, there is 3D interaction and offline reliability. Users can now explore maps in 3D, and Google will use vector graphics to dynamically draw the map on your device while you use it. You can now tilt in 3D by dragging on the map with two fingers, twist your fingers to rotate the map, and zoom.
A compass mode, for devices with a digital compass, will show the map in your perspective so you know what you're looking at. Also, with offline reliability, Google Maps will still continue to guide you if you lose connection. To start your trip, you'll still need to, however, have an Internet connection.
The update is available for Android 1.6 or later devices, but offline features require Android 2.0 or higher.
