Google Maps for Android gets update with Some user Friendly navigation menu. Gone is the standard ICS menu button. In its place is a menu launcher build directly into the Navigation UI. With the update, the menu button is now located on the Navigation screen, and when pressed, the menu items are now easily clickable with large icons. The new UI will definitely bring a better user experience to the app.
If you want the new update, just head over to the Google Play Store.
