How to toggle off and on the "predictive track" on a GTN unit

[TheGolfPilot]

Somebody asked me today how to toggle off and on the little blue line that goes in front of your plane that shows you where you are going to be after a period of time. It doesn't help that I don't know the name of it.
I didn't have an answer. Maybe someone here does

Is it in the trainer, because that is where i looked and had no luck.

The trainer may not be consistent with actual software releases that are installed in aircraft.

Likewise, the Pilot's Guide an owner holds may not be up to date either, if the software upgrades are sloppy...
