GPS Navigation Android phones have offered free, voice-guided GPS since October 2009, whereas the iPhone’s Maps app requires users to look at their handsets and read off directions as they drive. The iPhone has third-party apps with turn-by-turn voice guidance, such as Mapquest, but Android’s built-in method allows users to jump directly into navigation from address links in other apps. With the iPhone, you must manually copy and paste the address into your app of choice.
