You are the driver of a military vehicle, and your mission is to drive through a dangerous area, clear the mission and get out of the area.

The GPS Minimap -- Driving-Only Minimap will help you drive in the virtual world. You can use the virtual world to explore and get to know the area.

And that's what this mod does.
It toggles the minimap interface setting off if you are not in a vehicle and on if you are. It works as advertised out of the box; no configuration needed. It alaso has an optional CET keybinding to toggle between Driving-Only, On, and Off.
