Garmin GPS 2 Manual

							Reference Waypoints
To create a new waypoint manually without knowing its position coordinates,
you’ll need to enter its bearing and distance from an existing waypoint or your pre-
sent position.
To create a new waypoint by referencing a stored waypoint:
1. From the waypoint definition page, highlight ‘NEW?’, and press ENTER.
2. Enter a waypoint name, and press ENTER.
3. Highlight the ‘reference field’ (Fig. 35a), and press ENTER.
4. Enter a reference waypoint name (Fig. 35b) (or leave the field blank to use your present
position), and press ENTER.
5. Enter the bearing and distance of your new waypoint fromthe reference waypoint. 
6. Press ENTER to confirm the ‘DONE?’ prompt.Fig. 35a

							Editing Existing Waypoints
The waypoint definition page also allows you to change the name, coordinates,
comment, or reference waypoint field for a stored waypoint (Figs. 36a-36c).
To edit the coordinates, comment, or reference waypoint field: 
1. Highlight the field you want to edit, and press ENTER.
2. Enter new data, and press ENTER.

							Waypoint Comments
Each waypoint stored in the GPS II has a user-defined 16-character comment
field. The default comment is the UTC (or Greenwich mean time) date and time of
the waypoint’s creation. 
To change or add a comment:
1. Highlight the ‘comment’ field.
2. Press ENTER (Fig. 37a).
3. Make changes or enter a comment (Fig. 37b).
4. Press ENTER.Fig. 37a

							Renaming and Deleting Waypoints
The rename and delete function fields are located along the right side of the
waypoint definition page.
To rename a stored waypoint:
1. Highlight ‘RENAME?’ (Fig. 38a), and press ENTER.
2. Enter the new waypoint name (Fig. 38b), and press ENTER.
3. Press ENTER to confirm the ‘Yes?’ prompt.
To delete a stored waypoint:
1. Highlight ‘DELETE?’, and press ENTER.
2. Select ‘Yes?’, and press ENTER. Fig. 38a

							Scanning Waypoints
As you manually enter a waypoint’s name, the GPSII’s waypoint scanning feature
will automatically display the first numerical or alphabetical match of the character
you have entered to that point. This helps eliminate the need to always enter a way-
point’s complete name.
To scan waypoints from a waypoint field:
1. Highlight the ‘waypoint name’ field, and press ENTER.
2. Press the left side of the keypad to clear the name field. 
3. Scroll through the waypoints.
4. When you find the desired waypoint, press ENTER.The waypoint scanning feature
will offer the first waypoint
that matches the character or
characters you have entered to
that point. If you have more
than one waypoint that begins
with the same letter or num-
ber, move to the next character
position as needed.REFERENCE

							Selecting a GOTODestination
The GPS II provides four ways to navigate to a destination: GOTO, MOB,
TracBack, and route navigation. The most basic method of selecting a destination is
the GOTO function, which lets you choose any stored waypoint as the destination
and quickly sets a direct course from your present position.
To activate the GOTO function:
1. Press GOTO. 
2. Select the waypoint you want to navigate to (Fig. 40a), and press ENTER.
Once a GOTOwaypoint has been activated, the compass page or highway page
will provide steering guidance to the destination until either the GOTO is cancelled
or the unit has resumed navigating the active route (see page 53).
To cancel an active GOTO:
1. Press the GOTO key.
2. Highlight ‘CANCELGOTO?’ (Fig. 40b), and press ENTER. Fig. 40a

							Man Overboard Function
The GPS II’s man overboard function (MOB) lets you simultaneously mark and
set a course to a position for quick response to passing positions.
To activate the MOB mode:
1. Press GOTO twice. The GOTO waypoint page will appear with ‘MOB’ selected (Fig. 41a).
2Press ENTER to begin MOB navigation (Fig. 41b).
The GPS II will now guide you to the MOB waypoint until the MOBGOTOis
cancelled. If you want to save the MOB waypoint, be sure to rename it (Fig. 41c)
because it will be overwritten the next time a MOB is activated.Fig. 41a

							TracBack Navigation
The TracBack function allows you to quickly and easily retrace your path using
the track log automatically stored in the receiver’s memory. The advantage of the
TracBack feature is that it eliminates the need to mark waypoints along the way and
manually create and activate a route back to where you began your trip.
Once a TracBack route is activated, it will lead you back to the oldest track log
point stored in memory, so it’s usually a good idea to clear the existing track log at
the start of each trip.
To clear the track log and define a starting point for a TracBack route:
1. From the map page, press ENTER.
2. Highlight the ‘track setup’ option, and press ENTER.
2. Highlight ‘CLEARLOG?’ (Fig. 42a), and press ENTER.
3. Highlight ‘Yes?’ (Fig. 42b), and press ENTER. Fig. 42a

							To activate a TracBack route:
1. Press GOTO, and highlight ‘TRACBACK?’ (Fig. 43a).
2. Press ENTER.
Once the TracBack function has been activated, the GPS II will take the track log
currently stored in memory and divide it into segments called legs (Fig. 43b). Up to
30 temporary waypoints (e.g., ‘T001’) will be created to mark the most significant
features of the track log in order to duplicate your exact path as closely as possible.
The active route page will appear, showing a route from your present position to
the oldest track log point in memory. Steering guidance to each waypoint will be pro-
vided back to the starting point of your track log (Fig. 43c).Fig. 43a

							Tips on Creating and Using the TracBack Feature
To get the most out of the TracBack feature, remember the following tips:
•Always clear your track log at the exact point that you want to go back to (trail head,
truck, dock, etc.).
•The ‘record’ option on the track log setup page must be set to the ‘YES’ position.
•There must be at least two track log points stored in memory to create a TracBack
route.
•If there are not enough available waypoints in memory to create a TracBack route,
you will be alerted with a ‘waypoint memory full’ message, and the receiver will use
any available waypoints to create a TracBack route with an emphasis on the track log
closest to the destination (the oldest track log point in memory).
•If the ‘method’ option on the track log setup page is set to a time interval, the
TracBack route may not follow your exact path. (Keeping the criteria set to automatic
will always provide the most detailed TracBack route.)REFERENCE
