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 adjust 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.
You must know your GRI chain number and/or secondary stations 

to create a LORAN TD location. For more information read our 

LORAN TD Position Format Handbook, available at the Garmin 

Web site, at
