Offline maps mean you get super-fast maps and can save on data costs, anywhere you go.
Additionally, Nokia Maps will also include:
- voice guided turn-by-turn pedestrian navigation to take you right to your destination
- augmented reality view to reveal the places around you so you literally see where you need to go
- venue maps to see whats inside venues like shopping malls, airports and stadiums
- a link to Nokia Drive to start voice-guided car navigation directly from Nokia Maps
