If the active GRI Chain, secondary stations, or offsets were changed 

since the waypoint was created, the waypoint now references 

the active GRI chain and secondary stations and adjusts the TD 

coordinates accordingly. Remember that the GPS is not relying 

on the LORAN signal for navigation and actually converts the 

TD coordinate to a useful latitude and longitude coordinate 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 can download the 

LORAN TD Position Format Handbook from the Garmin Web site.
