How to get maps for off-line usage?

Google maps recently added offline caching of maps. But I can only see a way to download a small area. If I'm going on a long road trip soon, is there any way I can tell it to download all the data for the navigational route between point A and point B?

I'm looking for it to be used for Google Navigation for driving between the two points with turn-by-turn directions.

  • Well, I know how to select a specific (small) region in GMaps and download it for offline. I'm specifically looking for how to do that for a whole ROUTE between two points, which out needing to manually download innumerable small sections along the route, specifically for use in Google Navigation. – eidylon Sep 17 '12 at 19:18
  • Sure. My Nexus 7 (Jelly Bean) was able to sustain a certain time of being not connected (to a bluetooth tethered internet), I'm not really sure though if it is a viable solution for complete pre-loading and not just for temporary loss-of-cell-coverage situations only. For that you'd best bet on a real off-line solution like proposed in the answers in the linked question. At least there are no options (it's all auto-magically done), so I guess it's for bridging temporary no-cell-coverage situations only. Maybe the whole route is pre-downloaded but what will it do if you do a wrong turn? – ce4 Sep 17 '12 at 19:48
  • I don't believe any flavours of Android support true route caching. You can save a route as a link though. This question might provide some ideas: http://android.stackexchange.com/questions/27631/how-to-load-public-route-into-google-maps As a backup, I use an Open Street Maps based utility for true offline use, such as OSMdroid. – John T Sep 18 '12 at 13:01
