If the active GRI Chain, secondary stations, or offsets have been 

changed since the waypoint was created, the waypoint now 

references the active GRI-chain and secondary stations. You must 

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 LAT/LON 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 secondary stations 

to create a LORAN TD position. For more information, read our 

LORAN TD Position Format Handbook, available at the Garmin 

Web site (www.garmin.com/support/userManual.jsp.)
