There will be many times that you may need to enter data. An example is
naming a waypoint. The ROCKER Key is used to navigate through menu items
and to enter data.
Let’s combine a couple of lessons. We will create a new waypoint, enter a
waypoint name, and assign a symbol to the waypoint.
The term ‘Waypoint’ may be new to you. You will ﬁ nd the term Waypoint
is used frequently when talking about navigation. A Waypoint is a position
stored in the unit’s memory. Waypoints are used for direct navigation or to build
Creating or ‘Marking’ a waypoint with the GPSMAP 76 is easy. The unit has
to be turned on and receiving at least three satellites (or simulating navigation)
to mark a waypoint.Marking a waypoint:1. Press and hold the ENTER Key.When you held the ENTER Key the GPSMAP 76 captured it’s current posi-
tion, and displayed the Mark Waypoint Page. You will notice that the unit
assigned a square as the default symbol and a number as the default name. The
‘OK’ Button is highlighted, pressing the ENTER Key will store the new waypoint
using the default settings for the symbol and name, but let’s change them to
something more meaningful. Changing the symbol:1. Using the ROCKER Key, highlight the Symbol Field, then press ENTER.
2. Using the ROCKER Key, highlight the ‘Scenic Area’ symbol, then press ENTER.

Changing the name:1. Press the ROCKER Key right to highlight the Name Field then press the
ENTER Key.The Name Field will become active and the ﬁ rst zero will be highlighted.
Notice that there are now ten placeholders for alpha-numeric characters displayed. 1. Press the ROCKER Key to the left to clear the ﬁ eld.
2. Press the ROCKER Key up, scroll through the alpha-numeric list until the
letter ‘C’ is selected.
3. Press the ROCKER Key right to move to the next placeholder.
4. Press the ROCKER Key down, scroll through the alpha-numeric list until the
letter ‘R’ is selected.You should be starting to get the feel of it. Continue entering letters until you
have spelled the word CREEK. 5. With the letter ‘K’ highlighted, press the ENTER Key to accept the name.When you have ﬁ nished renaming the waypoint you will need to store it in
the units’ memory. To store the waypoint:1. Using the ROCKER Key, highlight the ‘OK’ Button and press the ENTER Key.These are the same steps that you will use to enter names and change numbers
and select options in all of the ﬁ elds in the GPSMAP 76. Here are a couple of tips:1. If you press and hold the ROCKER Key while scrolling through the alpha-
numeric list, it will move quickly.
2. You can scroll through the alpha-numeric list in either direction.
3. Don’t press the ENTER Key until you have ﬁ nished entering the data.
Remember, use the ROCKER Key to move to the next placeholder.

You should now have enough knowledge to navigate through the main pages,
Option Menus and enter data into your GPSMAP 76. Now let’s learn how to
The main use of a GPS is to be able to navigate to a known position. We have
already created a waypoint and named it CREEK. Let’s create another waypoint
on the Map Page using a different method, the Map Pointer.
Press the PA G E Key until the Map Page is displayed. Press the IN Key several
times until the Zoom Scale in the lower left corner of the Map Page reads 800ft.
The current GPS location is indicated by the triangle in the center of the map.To display the Map Pointer:1. Press the ROCKER Key any direction.Using the ROCKER Key you can pan the Map Pointer around the map. As
you move around the map, the direction and distance from the Map Pointer to the
current GPS location is displayed along the top of the map. To mark a waypoint using the Map Pointer:1. With the Map Pointer at a location on the map about one mile from your
current location, and not on a road or map feature, press the ENTER Key.The location of the Map Pointer will be captured and the New Waypoint Page
will be displayed. Change the waypoint name to MAP 1, and store the waypoint
in memory by highlighting the ‘OK’ Button then pressing the ENTER Key. Press
the QUIT Key to hide the Map Pointer and center the map on the current GPS
Now that we have a destination, navigating to it is just a step away.

Going to a waypoint:1. Press the NAV Key.
2. Highlight ‘Go To Point’ then press the ENTER Key.
3. Highlight ‘Waypoints’ then press the ENTER Key.
4. Highlight ‘MAP 1’ then press the ENTER Key.
5. Highlight the Goto Button then press the ENTER Key.The GPSMAP 76 is now navigating to the waypoint MAP 1.
For a GPS to navigate, it has to be moving. Fortunately you can simulate
movement in the GPSMAP 76. Press the PAGE Key until the Pointer Page is
displayed. Along the top of the Pointer Page there are several data ﬁ elds, the
Speed Field is located in the upper left corner. To simulate movement, press the
ROCKER Key up one time. This will set a speed of 10 miles per hour. If you
continue to press or hold the ROCKER Key, the speed will increase in 10 mph
increments. For our purpose, 10 mph is ﬁ ne.
The Pointer Page displays a Pointer and Compass Ring. The Pointer will
always point toward your destination (Bearing) while the Compass Ring reﬂ ects
the direction that you are traveling (Track). In short, when you are headed
directly toward your destination, the Pointer will be pointed toward the top of the
display, aligned with the vertical line on the Compass Ring. If you are no longer
heading toward your destination, the Pointer will turn away from the top of the
display to point toward your destination. To get headed toward your destination
again, turn until the Pointer is realigned with the vertical line in the Compass
Ring and pointed toward the top of the display.
The simulator will let you change the Track so that you can see what will
happen. Press the ROCKER Key to the right until your Track has changed about
40°. This will simulate a direction change to the right. The Pointer should now
be pointed toward the left of the display indicating that you need to turn to
the left to head toward the waypoint. This is exactly what will happen during
Selecting a waypoint for navigation

Press the ROCKER Key to the left simulating a left turn, until the Pointer
is realigned with the vertical line in the Compass Ring. You are now headed
toward the waypoint.
Now that we have now gone through the basic operation of the unit using the
simulator, it is time to do some actual navigation!To turn off the simulator:1. With the GPS Information Page displayed, press the MENU Key.
2. Select ‘Stop Simulator’ then press the ENTER Key.Before the GPSMAP 76 can be used for navigation, the receiver has to be
initialized. This process is automatic and will only take a few minutes.
Take the unit outside where it will have an unobstructed view of the sky and
turn it on. The unit will search for satellite signals and begin to gather and store
the information that it needs to become operational. This process should take
no more than ﬁ ve minutes. When the unit is operational, the message ‘3D GPS
Location’ will be displayed on the GPS Information Page.
If for some reason the unit is not able to gather the necessary satellite
information, an options page will be displayed. Select ‘New Location’ then
‘Automatic’ and allow the unit to continue initializing. This selection will force
the unit to search for satellites. It may take a little longer for the unit to become
operational using this method.
Starting to Navigate
With the unit on and displaying ‘3D GPS Location’ on the GPS Information
Page, mark a waypoint at your current location. Name this waypoint ‘HOME’,
assign the ‘Residence’ Symbol and store the waypoint.
