The improved Working Title GNS units are not natively implemented in the PC-6 and require the GNS Marketplace add-on (or a manual editing of the panel.cfg file, if on PC) for them to be implemented.

All aircraft included in the Base, Deluxe and Premium editions of the simulator ought to be utilizing the improved versions without additional steps being taken by the user (knowing about and installing the Marketplace add-on, editing panel.cfg).
