Yeah, that could very well be a hijack bug

Well, every other time I thought I observed such a thing, I was wrong

The little pointer in the map area should always be 'true north' up, the other pointer points to the direction of the next waypoint, but is relative to the current direction. So if it points up, you should be driving straight to the next waypoint, and it points down when driving away from it.

I don't have any waypoints on the player, I was just using it with the GPS and looking at the map area. Indeed, I figured out the bit about true north; It became obvious when I was heading toward Kittanning on route 28 (I took a ride to play with it) and it was pointed consistently toward what would be northeast if up was north.
