I did 
We were going camping at Perebere to a place i’m totally unfamiliar. I located the place on my Google Maps and pre-cached the area before leaving home as Internet won’t be available there.
Once this is done, i could find my location wherever i was during the travel on the map. I took the screenshot below when i was at Port-Louis going to Immigration square
Using this method, we managed to go to the camping at night to a location we were totally unfamiliar.
Well, I can say I am more than satisfied with my cheap Samsung Galaxy Pocket GT-S5300.
