The selected option begins to flash, waiting for you to change

The 957's position displays and waypoint navigation are based
on position information that it obtains from any one of the
following navigation sources:
•
GPS - choose this for GPS and WAAS
•
Phantom Loran - choose this if you want to see your posi-
tion displayed as loran TD's (the 957 calculates Phantom
Loran coordinates from the GPS coordinates)
•
external loran - choose this if a loran receiver is connected
to the 957
If your 957 is connected with an optional external radiobeacon differential
receiver, differential GPS corrections will automatically be used even if
you select Phantom Loran.
