Folks,
This is _totally_
implementation specific. As has been
mentioned in past posts, different manufactures treat the GC problem differently. From a very casual observation, the more “marine”
versions tend to always default to a GC route and the leisure markets go for
rhumb-line courses.
I use three separate units on board. Two hardwired (Raymarine 120,
and a MLR Differential unit) as well as a handheld Garmin 48. I also use two chart plotters (Raymarine 520
and Raytech software). The chart
plotters all default to great circle routes and only use the current position
as input from the GPS units (as well as COG, SOG, etc.)

And in the same Line tab (same GPS model), if you turn off
the Course line,
you end up with only the "rumb line" to your destination.
Which is not where the GPS is going to take you!
