It doesn’t matter what carrier someone uses, there is always the possibility of ending up somewhere where there is no signal and no roaming. In times like those, it is not comforting knowing that your only source for navigation requires a data connection of some sort.
Well, XDA Senior Member .xxx. has written a method that allows people to download maps off the web and store them on your Android device so you can access an atlas in case of emergencies or lack of data signal.
The process is pretty straightforward and completely free and just requires a little patience as it requires creating an atlas, rooting around on your sd card and placing files in specific places. .xxx. also has a method for Google Maps users where they can Precache a map in the labs menu. However, the drawback is that the precache map is only good for up to ten miles around the selected area. So if you need a wider range than that, it’s recommended that the first method be followed.
If an offline atlas is something you’d like to have, and it’s recommended if you intend on traveling to the boonies anytime soon, then you can find the method and information in the thread along with a list of apps that support user defined maps._________
