check the java's they might help you
example
Spoiler: public BigFuckMap()
{
posStart = new Vector3( 10.000, 0.000, 0.000 ); // Start car position
oriStart = new Ypr( 10.000, 0.000, 0.000 ); // Start car rotation
map = new GroundRef( Maps.Addon_Maps.BigFuckMap:0x00000001r );
//nav = new Navigator( -5.317-2.64, -15.996, 2.64, maps.test_track.smallmap:0x00000001r, maps.test_track.smallmap:0x00000002r, maps.test_track.smallmap:0x00000005r, 6, 8, 10 ); // GPS map
if you remove one of those lines they might remove it,not sure tho.never messed up with that.
