Nav4All is a free Turn-by-Turn navigation system, just like AndNav2, it uses continues internet connection to refresh its map. Nav4All uses the maps of NAVTEQ and is available for Android, Windows Mobile and BlackBerry. There are 56 languages and 101 voices that can be installed so the most languages are included.
Nav4All is a lightweight application which is pretty quick in use. The routes are planned nice and the most optimal. It also uses the internal GPS antenna, if the phone has one, or it will use a external. You can manage favorites like in any other navigation app, like Sygic or AndNav2.
