In short, this is all you have to know about AndNav2. The application works with information, provided by OpenStreetMap, which to a large extent is being enriched by the users (similarly to Wikipedia). This makes it not that correct at some places, and really detailed at others. The interface of the application seems handy and similar to the one of Google Maps. You can assure yourselves of this by watching the video below, or by downloading the alpha version of the application from here.
