If the active GRI Chain, secondary stations or offsets have been changed since the waypoint was
created, the waypoint will now reference the active GRI-chain and secondary stations and adjust the

and actually converts the TD coordinate to a useful LAT/LON coordinate (in the background) before
storing the waypoint to memory or using it for navigation. Because of this the unit can navigate to a
TD coordinate anywhere in the world.
