On Tuesday, GPS software outfit MapQuest announced on their blog that version 1.5.1 of MapQuest 4 Mobile for iPhone [App Store, Free] now incorporates a voice guidance feature within the app. The feature uses a voice to guide the user through directions and then confirms the directions once a turn has been made.
Other new features include Off-Route Assistance and Twin Tap to Zoom Out.
Apple's stock Google-powered Maps app on the iPhone is about to get some unexpected competition. AOL has just released MapQuest 4 Mobile for iPhone and iPod touch, available as a free application in the App Store. Self-described as a "leap forward in how people interact with maps, directions and local search," the app adds a few features not found in the Maps app.
