Almost everyone has had this experience, or nightmare navigating to a new destination. You decide to take your family or friends to a restaurant you've been hearing rave reviews about. Armed with Google Maps (or your choice of navigation), you are confident you'll reach your destination safe, sound, and, more importantly, fresh. Which you eventually do, but not in time to find out that the place closes shop at 8 p.m. If you had Google Maps' update app on your iPhone or iPad, that wouldn't have been a problem.
