second-by-second position readings.
The distance you are off a desired course in either direction, left or
right. Also referred to as ‘cross-track error’ or ‘course error’.
The current velocity at which you are travelling, relative to a ground
position. Also referred to as ‘ground speed’.
The estimated time required to reach a GOTO destination, or the next
waypoint in a route. Also referred to as ‘estimated time en route’.
Time to Dest—
The estimated time required to reach a GOTO destination, or the
ﬁ nal waypoint in a route.
Time to Next—
The estimated time required to reach a GOTO destination, or the
next waypoint in a route.
The recommended direction to steer in order to reduce course error
or stay on course. Provides the most efﬁ cient heading to get back to the desired
course and proceed along your route.
The direction of movement relative to a ground position. Also referred to
as ‘ground track’.
A running tally of distance travelled since last reset. Also see
Total Average Speed—
Average speed of unit for both moving and stopped speeds
since last timer reset.
Total Trip Timer—
Total time the unit has been in operation since last reset of the
Tu r n —
The angle difference between the bearing to your destination and your
current track. ‘L’ indicates you should turn left, ‘R’ indicates you should turn right.
The degrees indicate the angle you are off course.
Velocity Made Good. The speed you are closing in on a destination along a
desired course. Also referred to as the ‘vector velocity’ to your destination.

Approaching Turn —
is displayed when you are nearing a turn in a route.
Arriving at Destination —
is displayed when you are nearing your destination.
Batteries Low —
when displayed you have less than 10 minutes of battery left.
Cannot display all found, use city or postal code —
The unit found too many items to
display. Narrow the search using the city or postal code.
Deep Water —
The water is deeper than the amount set in the Deep Water Alarm.
Database Error —
Internal problem with the unit. Contact your dealer or GARMIN
Customer Service to have the unit repaired.
Dragging Anchor —
is the message displayed when the distance set in the Anchor
Alarm is exceeded.
Lost Satellite Reception —
The unit is unable to continue receiving satellite signals.

Loran TD System
LORAN C is a radio navigation aid operated and maintained in the United
States by the United States Coast Guard. The name LORAN is an acronym for
“LOng RAnge Navigation”. The LORAN system covers the entire United States
and the U.S. Coastal Conﬂ uence Zone. From the perspective of a mariner, the
system is used for ocean and coastal navigation. It can be used as a supplemental
system for harbor and harbor approach navigation, and it is used for inland
navigation by recreational vehicles.
LORAN TD Feature
The LORAN TD (Time Delay) feature eases the transition from using LORAN
to using GPS. The GPSMAP unit automatically converts GPS coordinates to
LORAN TDs for those who have a collection of LORAN ﬁ xes for favorite ﬁ shing
spots and other waypoints recorded as TDs. You can display your position as a TD
or enter waypoints as TDs. The accuracy to be expected from this conversion is
approximately thirty meters. When the unit is placed in the LORAN TD format
mode, it simulates the operation of a LORAN receiver. Position coordinates may
be displayed as TDs, and all navigation functions may be used as if the unit was
actually receiving LORAN signals.
Using the LORAN TD Format
When creating new waypoints using LORAN TD coordinates, you must set
the correct LORAN chain number and secondary stations in the Setup TD ﬁ eld
before storing the waypoint. After the waypoint is stored in unit memory, it
will always reference the LORAN chain number and secondary stations currently
selected in the Setup TD ﬁ eld. If you enter a different LORAN chain number,
change the secondary stations or offsets in the Setup TD ﬁ eld, the active waypoint
information will reﬂ ect those changes. Since the GPS 76 does not rely on the
LORAN signal for navigation, it can reference a different GRI chain and/or
secondary stations and still navigate to the location stored in memory.

The LORAN Position Format ﬁ eld is located under the Units tab in the Main
Menu. The ‘LORAN TD Setup’ window contains the ﬁ elds to select the Loran
GRI-Chain Number, Primary and Secondary Stations, and TD Offsets.To setup Loran TD from the Main Menu:1. Using the ROCKER, highlight the “Location Format” ﬁ eld on the ‘Location
Tab” and press ENTER.
2. Highlight ‘Loran TD’, press ENTER.
3. To change the settings of any of the ﬁ ve ﬁ elds, highlight the ﬁ eld, press
ENTER select/enter the desired setting then press ENTER.
4. When done, press the PAGE Key to return to the Main Menu.If the active GRI Chain, secondary stations or offsets have been changed since
the waypoint was created, the waypoint will now reference 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 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.
