Actualy some GPS have built in compasses. So some are and some are not. Like I said you have to be moving for some of them to work right. I am not familiar with the magellan's enough to coment on them. I used to work for Garmin though so I know alot about them.
It doesn't matter.A GPS is pretty much useless without a compass. With a compass, today's GPS units are gold. You can walk from pointA to point B and all points in between with a compass and be right on the money. Without, a compass it's just a guess.
Actually, if I could only carry one item and had to pick between a GPS and a compass, I'dtake the compass. It never fails.
