AVEC is a Vector Map GPS Navigator by Art.

Quote:

AVEC is a Vector map viewer capable of displaying and navigating mapss in the common Polish format maps. This 1.50 kernel version can also receive location from a GPS device and display your location on the map. If the map file has street information, the program tells you what street you are in, or lookup the name of a street selected with the crosshair.
