Last week I took my Moto Droid with me to my hunting spot in northern Michigan. I figured I would set our campsite as one of my favorites so I don't get lost. So, I'm standing outside of my car click on "Maps" the little satellite icon pops up but nothing is drawn on the screen. Where I am at there isn't any cell phone coverage. Does my Droid GPS need 3G coverage to draw the maps? When I had my Garmin it didn't matter where I was it just worked. Does anyone know of a better app that can help with this or am I just SOL? Thanks!
