Joe,
That would depend on the firmware in your particular GPS receiver. You
could determine the answer by asking it to point to a series of
waypoints all at your current lattitude. If it calculates great circle
the initial heading will be more toward the nearer pole for the more
distant waypoints. If not, it will point true east or west for all of
them.
