If the active GRI Chain, secondary stations or offsets have been changed since the waypoint was cre-

ated, the waypoint now references the active GRI-chain and secondary stations and adjust the TD coordi-
nates accordingly. Remember that the GPS is not relying on the LORAN signal for navigation and actu-
ally 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.

For more information on Loran TDs, you may download Garmin’s “Loran TD Position Format Hand-

book” from the Garmin Web site.
