@W0LFB3AT5: You can download part of Google's maps for offline use. Doing that in advance decreases data usage to mere kilobytes, and if you also set the location service to device only your data usage will become effectively zero for navigating.

@NotMeNotYou: huh!...

You seriously could use maps on your phone for offline use? I've been using maps online since I got my car.

I'm sorry, I don't mean to sound like I'm mental challenged, but is it built in the phone for offline?
