I tried andnav when i use it with wifi and data connection turned off, it says cant search google..navigator gets it's info from satellites and needs google maps to work (which needs internet). I'm not sure how they work together (I'm a newbie not a techie). I believe wireless locates you're coarse location and the gps finds your exact. But I do know "latitude" is just for tracking your friends (with their permission). Just trying to help.(and I luv my gps navigator!)
