The location of each available satellite is displayed over two location rings.
The outer ring represents the horizon, the inner ring represents 45° above the
horizon and the center represents directly overhead. When the unit is using
a satellite for navigation, the satellite number will become highlighted on the
location rings. The unit can be set to display satellite location with North, or your
current track toward the top of the display.
Satellite Strength Indicator Bars
The Satellite Strength Indicator Bars not only show the strength of the signal
being received, they also show the status of the signal. The bars will be either
shaded with a light grey, or ﬁ lled with solid black. If the bar is grey, it means
that the GPS is receiving a signal from the satellite and is in the process of storing
orbital data provided in the GPS signal. When the bar turns solid black, the GPS
is using the satellite signal for navigation. A “D” in or above the bar means that
differential corrections are being applied to that satellite.
Date, Time and Current Location
The GPS gets date and time information from the satellites. The satellites
are equipped with an atomic clock that is very accurate. Since the GPS clock
is derived from timing information sent from the satellite, the GPS clock is also
When the GPS receiver has achieved a 2D or 3D GPS Location, the current
location will be displayed in the selected Location Format.

To activate the Options Menu from the GPS Information Page, press the
MENU Key. To select an option, highlight the desired selection then press
ENTER.Start/Stop Simulator —
This option is used to Start or Stop the Simulator.
Track Up/North Up —
This option determines if the satellites are displayed with
the rings oriented with North toward the top of the display or your current
track toward the top of the display.
New Elevation —
This option can be used to enter a different elevation. If
the GPS has a 2D GPS Location, entering a known elevation can increase
the GPS accuracy.
New Location —
If you have moved the unit to another state, province, or
country, and you are having trouble locking onto satellite signals select ‘New
When you select ‘New Location’, an options menu will be displayed. This
menu contains the options ‘Automatic’ or ‘Use Map’. If you select ‘Automatic’
the unit will switch to AutoLocate and begin searching for satellites. This
method can take up to ﬁ ve minutes for the unit to begin navigation.
If you select ‘Use Map’, you can use the Pointer on the Map Page to select your
approximate location and the unit will continue to acquire satellites normally
using the almanac for satellite reference. Using this method, the unit does not
need to reinitialize and should receive satellite signals quickly.
If the unit is in the ‘Simulator’ mode, the ‘Use Map’ feature will allow you to
move the simulated current location.

The GPS 76 comes with a factory-loaded marine point database that includes
marine navaids and major cities. This can be replaced with marine navaids, cities,
and points of interest using GARMIN MapSource products.
Changing the Zoom Scale
You can change the Zoom Scale on the Map Page allowing you to either view
a smaller area in greater detail or a larger area with less detail. As referred to
in this manual, when you decrease the Zoom Scale you will view a smaller area
with greater detail. The current Zoom Scale setting is displayed in the lower left
corner of the Map Page. If ‘Overzoom’ is displayed under the scale, no further
map information is available.To change the Zoom Scale:1. Press the IN Key to decrease the Zoom Scale.
2. Press the OUT Key to increase the Zoom Scale.

If you select ‘Off ’, the items for that option will not be displayed on the Map
Page. If you select ‘Auto’, the GPS 76 will automatically determine the zoom
level at which to display the selected items. If you select a scale setting, the
items will be displayed on the map only when the Map Zoom Scale is at or
less than the selected scale .
As an example, if you select 500 ft as ‘Zoom’ Scale setting, the selected items
will only be displayed when the Map Zoom Scale is at 500 ft or less. Setup Map — ‘General’ TabThe ‘General’ Tab contains the settings for Detail, Orientation and Auto Zoom.
Below is a description of each feature. To change a setting, highlight the
appropriate ﬁ eld then press ENTER. Make your selection, then press ENTER
to accept the new selection. Detail —
Settings: Most, More, Normal, Less, and Least. The Detail settings
allow you to control the amount of map data displayed on the unit. If you

Settings: North Up, Track Up, and Course Up. This option
allows you to determine how the map is displayed. If ‘North Up’ is selected,
North will always be at the top of the display. If ‘Track Up’ is selected, your
current track will always be toward the top of the display. If ‘Course Up’ is
selected, the active course line will always be toward the top of the display. If
you have ‘Course Up’ selected and do not have an active course, your current
track will be toward the top of the display.
