North Up mode also requires your ship's heading data. In North Up mode, north or 000° is always at the top.
When your ship changes course, the heading marker will move too.
Targets will not arc across the screen, but will have a new relative motion line as your ship steadies on the new course.
Even though a North Up display has the same alignment as a chart, most small boat navigators prefer a Head Up or Course Up display.
