RoadMap

RoadMap is a program that supports car navigation: It displays a map of the streets, tracks the position provided by a NMEA-compliant GPS receiver, identifies the street matching the position and announces the name of the crossing street at the next intersection. A rudimentary trip feature allows RoadMap to display some basic navigation information (distance to the destination, direction, speed, etc.). Voice messages are generated that duplicate some of the screen information. RoadMap is written in C, runs on Linux and Unix, iPAQ and Zaurus. It is released under GPL license.

The device uses many open source software released under GPL license, including a compiler toolchain used to build all the software, the Linux kernel for ARM, with modifications by TomTom, BlueZ libraries and utilities, Other third party software under GPL license, and TomTom software under GPL license.
