Google Adds The Ability to 'Download a Map' Area [googleblog.blogspot.com]
But a little advance planning and “Download map area” can help. Before you take your trip, while you still have access to WiFi or data coverage, you can open up any Places page in the world, click “More” to get the Place page menu, and download Google’s maps for a 10-mile radius.
The download can take as little as a minute or two. This download stores only the base map tiles and the landmarks on the map, so you still need a data connection to see satellite view and 3D buildings, search for Places and get directions. But we hope the level of detail available will help you find your way!
