In Course-up orientation, what rotates with the vessel's course?

In Course-up orientation, the display is rotated so that your vessel’s direction of travel is always toward the top of the screen. As you steer and your course changes, the whole display rotates to keep that forward direction at the top, so the top of the screen moves with the vessel’s course. This makes it easier to judge where you’re heading and how other contacts relate to that heading. If the top stayed fixed, you’d be in a north-up view rather than course-up, which isn’t how this mode works. Range rings and other elements rotate with the display, but the key point is that the top edge aligns with your current course.
