Is it possible to download a google map of an area and store on the Droid?
If so can Nav be used when network coverage is lost on a store map?
Data Connection Loss - Google Mobile Help
If you lose your data connection while using Google Maps Navigation (Beta):
- Navigation and voice guidance will continue as long as you do not deviate from your prescribed route, but underlying map tiles may not load.
- The navigation icon in the notification bar will be gray instead of blue.
- If you deviate from your route, you will not receive a reroute until you re-establish a data connection.
Google Maps Navigation (Beta) works by communicating through your Android-powered device's mobile data connection to access routes, traffic, geographical and business information, etc.. If you're driving in an area with spotty or no data connectivity, you'll still be able to use Google Maps Navigation (Beta) through the use of pre-fetched map data. Pre-fetched map data for your route is passively downloaded and stored locally on your device, and Google Maps Navigation (Beta) will rely on this data when your device loses its data connection.
