Location MFD is my warp drive!:lol: You set the major body, Earth Mars, Etc, then the inclination. Shift-Enter places your ship in that Location.Don't know what this Location MFD is, but you can manually set Orbit HUD reference by setting Mars as reference in the Orbit MFD, and from there press the HUD button.
Note that the prograde/retrograde/etc. autopilots will still use the most gravitational attracting object as reference, no matter what you see on the HUD.
