Roadnav 0.18

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 cars 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.
Main features:
- 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 (drivers 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
