read and write tracks
iGo8 is the successor to the "iGo My way" software package that is reasonably prolific for GPS devices manufactured by Mio, Sony, LG, as well as many other small manufacturers. iGo8 is notable in that it has full 3D rendering of terrain as well as buildings and landmarks for most large cities. The software can also be bought pre-loaded on a mico-SD card for use in many PPC phones that are GPS enabled.
The track format used by iGo8 is rather rudimentary, consisting of a list of coordinates and a time resolution of 1 second. While iGo8 supports exporting tracks to GPX format, importing tracks is not natively supported.
Track identification number.
This option isn't entirely clear. It appears to be a unique number for each track that is used for coloring on the main display. So if you want two tracks to have different colors, set the track numbers to different values.
