The same will happen with a GPS, unless you know how to use cross

It will? How's that? My GPS has a few chart plotters connected to it.
They all have at least one, even without the chart plug. You know where
the waypoint is. It draws a line you follow, even if you're steering it by
hand.

How do you spiral in with this? You might be looking at the wrong display!
