Roadnav is an in-car navigation system that can run on a variety of operating systems like Linux, Windows, and Mac OS X.

Roadnav can obtain a car's present location from a GPS unit, plot street maps of the area, and provide verbal turn by turn directions to any location in the USA.

Roadnav uses the free TIGER/Line files from the US Census Bureau to build the maps, along with the GNIS state and topical gazetteer data from the USGS to identify locations.

Here are some key features of "Roadnav":
Generates street level maps for the US
Interfaces with GPS units to display your position in real time
Verbal turn by turn directions to any place in the US. Automatically recomputes directions if you miss a turn.
On screen keyboard
3D (driver's perspective) view mode
Daytime and nighttime color schemes
Automatic day/night mode switching
Plots nearby landmarks and points of interest
Can operate offline (without an Internet connection)
Antialiased output
Supports multiple operating systems including Windows, Linux, and Mac OS X
Uses freely available data from the US Census Bureau and the USGS
Appearance can be customized with skins
Can output status information to LCD devices through LCDproc
