MapQuest yesterday announced the launch of a major update to its MapQuest 4 Mobile GPS application for the iPhone, bringing basic turn-by-turn voice guidance and off-route assistance to the free application.
The new update also adds the ability to double tap to zoom out on maps, as well as a new energy saving mode that dims the screen during voice guidance.We're pleased to announce that basic Voice Guidance is now available on our MapQuest 4 Mobile iPhone app. This is an exciting feature that really differentiates us from most other free navigation apps available for iPhone.
MapQuest also offers a more advanced subscription-based GPS navigation application, MapQuest Navigator, priced at $0.99 for the application and $29.99 per year for service. Shorter subscriptions are also available.
