Hey Casey, are you able to keep the Compass Effect enabled after moving the NC and GPS to the boom?
Man, I hope so. of course, I tested .88 yesterday with waypoint/POI routes, and completely spaced out on that, and had CE set to zero.
Seriously though, the new position of the compass shouldn't prevent you from allowing it effect yaw.
