mmh im not sure but i think that Fargo talk of another problem:
Maybe he ask how see his own guy on the map when he make a mission in the editor...
If its your real prob then its easy: when you start ofp for make your mission dont go immediatly in the editor but open a single mission first (long ago i played the one where you have to stole the car on Malden, quick to load!), then the gps is actived and if you go in editor you will see yourself in the map... If you go immediatly in editor the gps dont work, its an old ofp bug!
If you need then do as me:
- place a mm1 soldier in desert island and save the mission in solo missions, name it "gps initialization for editor", then you can load the mission very quickly and once it start just shoot the ground and exit... (mm1 soldier cause it require only one hand for > loading the mission/killing yourself/closing the game/exiting
)
