G-Map U.S. West and G-Map U.S. East are new iPhone Apps that brings turn-by-turn GPS navigation to the iPhone. The app costs $19.99 and brings many advanced navigation features including address search, distance countdown to each turn, POIs, the ability to avoid certain roads such as tolls roads, highways, route recalculation, among other features such as 3D intersections (select intersections). However, the app does have one fairly large raw back: it doesn’t have voice prompts. A future update should fix these problems, really bringing GPS navigation to the iPhone.
