I have updated the Topic to better represent what this Thread was intended to be about.
The Orientation of the MAP & Compass Rose, as depicted in Garmin GPS systems, in particular the GTN750 in MSFS
.
Garmin Trainer --------------------------------------------------- PMS50 GTN750
- Garmin Trainer has the Compass ROSE orientated to MAGNETIC North
- MSFS GTN750 has the compass rose orientated to True North
Note: In BOTH cases, the Map is orientated to TRUE North (as expected)
Plane is flying 360 Magnetic
