Android and iOS both come with Google Maps, but the features included in Android are far more advanced - no surprise given Google's close ties to that platform.
While Google Maps in iOS is limited to displaying directions on a 2D map, the latest version of Google Maps in Android includes a separate Places app for looking up nearby points of interest, a Latitude widget for seeing where your friends are, and a Layers option that displays Wikipedia, transit lines, and other information on top of the maps interface.
If you limit your GPS use to the built-in app only, Android wins this round. But if you're looking for a proper turn-by-turn navigation to use, iOS wins for sheer variety.
The major apps offering turn-by-turn navigation in Android are Sygic Mobile Maps, CoPilot Live and WhereiS Navigator - the latter is a subscription $15-a-month Telstra service that downloads maps on the fly like Google Maps.
iOS, on the other hand, has close to a dozen turn-by-turn navigation apps with Australia and NZ maps - in addition to having the ones that are available for Android, this includes TomTom and Navigon, as well as the new 3D Sygic Aura Drive, which is more full-featured than standalone GPS devices.
Android has many apps that take advantage of the GPS chip, but here too iOS trumps it.
