Navit is a open source (GPL) car navigation system with routing engine. It s 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. The GTK+ or SDL user interfaces are designed to work well with touch screen displays.
