Before last summer's tour, I bought a Nexus 7 to have access to Google maps off line; I could store 6 large tiles at once, which was enough to stay at least a couple of days ahead, so I'd be ok if I didn't have wifi for a day. There's been an upgrade (I'm not sure when, as I wasn't using mapping for a while) which broke offline map storage; now I can only store 1 much smaller map tile, so that I do many rides that won't fit on the maps I can store on my tablet.
The upgrade also broke OSMAND, but I was able to reload that, and I have all of North America's Open Street Maps stored. However, I don't like their mapping nearly as much. Is there an app that will allow me to store 6 tiles of Google Maps locally (or more than 6)? I'm happy to pay for it, but I do want Google Maps.
