+
+AutoName: Navit
+Description: |-
+    Its modular design is capable of using vector maps of various formats for
+    routing and rendering of the displayed map. It’s even possible to use multiple
+    maps at a time. While Navit supports all major platforms, there is a fork
+    specializing on an easy-to-use, Android-only solution:
+    https://f-droid.org/packages/com.zoffcc.applications.zanavi.
+
+    The routing engine not only calculates an optimal route to your destination, but
+    also generates directions and even speaks to you.
+
+    Navit currently speaks 27 languages. You can help translating via the web-based
+    <a href="http://translations.launchpad.net/navit/trunk/+pots/navit">translation page</a>.
