Google has pushed out an updated version of Google Maps for Android which now supports turn-by-turn walking navigation. It’s sort of like the GPS navigation you could previously use in a car — but for directions for getting from here to there on foot.
Google had previously offered walking directions, but not turn by turn navigation.
Walking Navigation is still in beta, so don’t be surprised if Google occasionally directs you to walk down a road that doesn’t have sidewalks.
The new version of Google Maps also has a persistent search bar at the top of the screen allowing you to filter your results or tap on icons to bring up the Places or Layers screens, or zoom to your current location.
You can grab the updated version of Google Apps for Android 1.6 and up from the Android Market.
