Roadnav 0.17: Multi-OS GPS Navigation System

This, I think, is a rarity... A multi-OS (Linux, Mac OS X, and Windows) Open Source GPS navigation application.

Roadnav 0.17

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.

The current version was released on Feb. 24.
