Using the Position Page
Walk briskly for 3 - 4 minutes and watch the position page. This is a good opportunity to compare the Com­pass Tape at the top of the page and the Track (the direc­tion that you are moving), as long as you are walking briskly they should be a direct reflection of one another. The speed that you are traveling, distance you have trav­eled, and the altitude are also displayed on the upper por­tion of the screen. The lower portion contains your lati­tude and longitude, notice that the current position is con­tinually updating as long as you are moving. The current time is displayed at the bottom of the page.

The Map Page shows your present position as a dia­mond icon in the center of the map. The house symbol labeled ‘HOME’ is the waypoint that you created when you ‘MARKED’ your position, the line connecting the two is called the ‘TRACK LOG’.
1. Now turn approximately 90° to your left and continue walking for another 2 - 3 minutes. Notice how the dis play changes always keeping the direction that you are traveling toward the top of the map and your track log updates continually leaving a breadcrumb trail of where you have been.
Going to a Waypoint
Once you’ve stored a waypoint in memory, you may return to it by performing a GOTO. A GOTO is a straight­line course from your present position to the destination you’ve selected. Let’s navigate back to our starting posi­tion, the HOME waypoint.
To select a GOTO destination:
1. Press
GOTO
.
2. Highlight the HOME on the ‘G-H-I’ tab and press
ENTER
. You’ll notice that you’ll automatically return to the Map Page, and a straight line will connect your current position to the HOME waypoint.
Let’s continue by moving to the Compass Page:

Compass Ring
Track Over Ground
Whenever you select a destination waypoint, the GPS 12CX provides graphic steering guidance with the Compass Page (the default navigation page). The “com­pass ring” in the middle of the page acts much the same as the “compass tape” at the top of the Position Page, it provides a graphic representation of your present track (TRK). The “pointer” is a graphic representation of the direction or bearing (BRG) to the destination waypoint, and points in the direction you need to travel.
The pointer does not function as a magnetic compass. Navigation is active only while the GPS 12CX is moving.
For instance, if the “pointer” is pointing toward the top of the display then you are heading toward the des­tination waypoint. If the “pointer” is pointing in any other direction, turn in the direction of the “pointer” until it is pointing to the top, then continue in that di­rection.
The bearing (BRG) and distance (DST) to the desti­nation waypoint are displayed at the top of the screen, the track (TRK) and speed (SPD) are shown below. The default ‘ETE’ field at the bottom of the screen, is a user selectable field that can provide a variety of navi­gation information.
As you get closer to ‘HOME’, you will be alerted to

Signal Strength Indicators
The GPS 12CX’s Satellite Page displays the status of various receiver functions. The status information will help you understand what the GPS 12CX is doing at any given time, and will tell you whether or not the receiver has calculated a position fix.
Sky View and Signal Strength Bars
The sky view and signal strength bars give you an indication of what satellites are visible to the receiver, whether or not they are being used to calculate a posi­tion fix, and the signal quality. The satellite sky view shows a bird’s-eye-view of the position of each avail­able satellite relative to the unit’s last known position. The outer circle represents the horizon (north up); the inner circle is 45º above the horizon; and the center point is directly overhead.
You can use the sky view to help determine if any satellites are being blocked, and whether you have a current position fix (indicated by ‘2D NAV’ or ‘3D NAV’ in the status field). You can also set the sky view to a track up configuration by changing the ‘orienta­tion’ option on the Map Page. (See pg. 16 for setup instructions.)
When the receiver is looking for a particular satel­lite, the corresponding signal strength bar will be blank and the sky view indicator will be highlighted. Once the receiver has found the satellite, a strength bar will appear indicating that the satellite has been found and the receiver is collecting data from it. The satellite num­ber in the sky view will no longer appear highlighted. As soon as the GPS 12CX has collected the necessary data to calculate a fix, the status field will indicate a 2D or 3D status.

EZinit Option Prompt (continued)
(The EZinit prompt will automatically appear if the receiver needs to be initialized. The prompt may also appear during normal use if the antenna is shaded or the unit is operated indoors.)
Battery Level Indicator
The Satellite Page also features a battery level indi­cator, located to the left of the sky view, which displays the strength of the unit’s batteries.
The battery level indicator is calibrated for alkaline batteries. Ni-Cad and lithium batteries will not display accurately.
The GPS 12CX features a rechargable internal lithium battery that will maintain the unit’s memory for several months without batteries installed. When new batteries are installed or the unit is operated on external power, the internal lithium battery will renew its charge.
Backlight Bulb Icon
The GPS 12CX features three level (off, low, high) full-screen backlighting. Anytime the backlight is on, a bulb icon will be displayed on the satellite page.
Emergency Erase Function
You may erase the GPS 12CX’s memory in four quick steps. This will cause all stored data to be de­leted, including routes, waypoints, and the track log.

Position Page
The second page in the GPS 12CX’s primary page sequence is the Position Page. This page shows you where you are, what direction you’re heading, and how fast you’re going, and it’s most useful when you are traveling without an active destination waypoint. The Compass Tape at the top of the page is a graphic repre­sentation of the track, and indicates the direction you’re heading while you’re moving.
Directly below this display are the track, speed, trip odometer and the altitude (default) fields. Below these fields is the position field. The position field indicates your current latitude and longitude in degrees and min­utes. The GPS 12CX uses this basic information to mark exact positions as waypoints, which help guide you from one place to another. The bottom of the page contains a 12- or 24-hour clock.
Both the trip odometer and the altitude fields are user selectable, and both offer a trip odometer, trip timer, and elapsed time. This way, you can always be sure of viewing this information regardless of the option you’ve selected for the other user-selectable field.
The following user-selectable options are available on
the Position Page:
Trip Odometer (TRIP)— total distance traveled since reset.
Trip Timer (TTIME)— total (cumulative) time in which a
ground speed has been maintained since last reset.
Elapsed Time (ELPSD)— total time in hours and min
utes since last reset.
Average Speed (AVSPD)— average speed traveled since
last reset.
Maximum Speed (MXSPD)— maximum speed traveled
since last reset.
Altitude (ALT)— v ertical distance above mean sea lev el.
To reset TTIME, MXSPD, AVSPD, or TRIP:
1. Highlight the user-selectable field, and press

The Map Page shows your current position and sur­roundings, and provides you with a target cursor that lets you pan ahead to nearby waypoints, determine the distance and bearing to a map position or nearby way­point, and mark new waypoints while you navigate.
The map displays your present position as a diamond icon, with your track and/or route displayed as a solid line. Nearby waypoints are represented as squares or icons with the waypoint name listed above. You may select the features that are displayed on the map through the map setup submenu page (see page 16 for more information).
The four corners of the Map Page are used to display navigation data, including the bearing and distance to a destination waypoint and your current track and speed over ground. The two fields at the top corners of the map show your bearing and distance to one of three selectable destinations: an active destination waypoint, a highlighted waypoint, or the panning target crosshair. If you are not navigating to a waypoint or using the pan­ning function, the top data fields will not be displayed. Your current track and speed are shown at the bottom corners of the display.

Highway PageHighway Page
Compass PageCompass Page
Compass Page
Compass PageCompass Page
• The Compass Page (default) provides a directional pointer indicating the bearing to your destination and a rotating compass ring which shows your di­rection of travel (track) at the top of the ring. The Compass Page provides better guidance for car travel, hiking, or biking; where straight-line navi­gation is often not possible.
• The Highway Page provides a graphic highway display that shows your movement relative to the desired course, with an emphasis on your cross track error ( the distance and direction you are off course). The cross track error (XTK) is depicted on a course deviation indicator (CDI) (see pg. 40). The Highway Page is well-suited for boating or some types of off-road recreation where straight line navigation is typically possible and maintain­ing a specified course is desirable.
Both pages provide a digital display of the bearing and distance to the destination, and your current speed and track over the ground. You can switch to either Navigation Page at any time.

2. Use the keypad to scroll through the possible options.
The following data options are available:
Estimated Time Enroute (ETE)— the estimated time remain
ing to reach your destination based on your present speed and
track.
Estimated Time of Arrival (ETA)— the estimated time of day
at which you will arrive at your destination based on current
ground speed and track.
Course to Steer (CTS)— the recommended course to follow
in order to reduce cross track error and stay on course. Pro-
vides the most efficient heading to get back on course and
proceed along your route or GOTO.
Crosstrack Error (XTK)— the distance you are off the desired
course in either direction, left or right. This f ield will give y ou a
digital readout of the data depicted by the CDI.
Velocity Made Good (VMG)— the speed you are closing in
on a destination along the desired course. Also referred to as
the ‘vector velocity’ to your destination.
Turn (TRN)— 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 Compass Page provides better steering guidance than the Highway Page for travel at slower speeds (e.g., walking), travel with many directional changes and when it’s not necessary to follow an exact course.
The bearing (BRG) and distance (DST) to the way­point are displayed at the top of the page, below the destination waypoint name. The distance displayed is the straight-line distance from your present position to the destination waypoint. The bearing indicates the ex­act compass heading from you to the destination.
The middle of the page features a rotating “compass ring” that shows your track, or course over ground while you are moving, with a “pointer” to the destination dis­played in the center. The “pointer” shows the direction of your destination relative to the direction you are mov­ing. For instance, if the arrow points up, you are going directly to the waypoint. If the arrow points any direc­tion (left, right, down, etc.), turn toward the arrow un­til it points up. Then continue in that direction.
The bottom of the page shows your track (TRK), speed (SPD), and a user-selectable field for ETE, ETA, CTS, XTK, VMG, or TRN.
When you are one minute away from your destina­tion (based on your current speed and track over ground), the GPS 12CX will alert you with a flashing on-screen message box.

Graphic Highway
The GPS 12CX’s Highway Page provides graphic steering guidance to a destination waypoint, with a greater emphasis on the straight-line desired course and the dis­tance and direction you are off course. The bearing and distance to a waypoint—along with your current track and speed—are displayed at the top of the screen.
As you head toward your destination, the middle of the screen provides visual guidance to your waypoint on a moving graphic “highway.” Your present position is rep­resented by the diamond in the center of a course devia­tion indicator (CDI) scale. The line down the middle of the highway represents your desired track. As you navi­gate toward a waypoint, the highway will actually move— indicating the direction you’re off course—relative to the position diamond on the CDI scale. When the highway is pointing straight up the screen, the waypoint is directly ahead. If the destination waypoint is to the left, the top of the highway will lead to the left, and vice versa. To stay on course, simply steer in the direction the highway leads (left or right) until the highway leads straight up the page.
If you do get off the desired course by more than 1/ 5th of the selected CDI range, the exact distance you are off course will be displayed where the CDI scale setting normally appears. If you get too far off course (the highway has disappeared off either side of the high­way display), a message box will appear to indicate what course to steer to get back on course. (For infor­mation on how to set this scale, see pg. 40.) As you approach a waypoint, a horizontal “finish line” will move toward the bottom of the highway. When the finish line reaches the CDI scale, you’ve arrived at your destination.

Selecting a GOTO Destination
The GPS 12CX 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.

Clearing the Track Log
TracBack Navigation
GARMIN’s patented TracBack feature allows you to quickly retrace your path using the track log automatically stored in the receiver. This feature 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
TracBac k route:

2. Highlight ‘CLEAR LOG?’, press ‘Yes?’, and press
To activate a T racBack route:
1. Press

,
2. Highlight the ‘OPT’ tab.
3. Highlight ‘TRACBACK’ and press
Once the TracBack function has been activated, the GPS 12CX will take the track log currently stored in memory and divide it into segments called legs. Up to 30 temporary waypoints will be created to mark the most significant features of the track log in order to duplicate your exact path as closely as possible. These points will be indicated by ‘T###’ (e.g., ‘T001’) on the waypoint list, and by a ‘T’ symbol on the Map Page.
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 provided back to the starting point of your track log.

Tips On the TracBack Feature
• Always clear your track log at the exact point that you want to go back to (trail head, truck, etc.).
• The ‘RECORD’ option on the track log setup page must be set to ‘WRAP’ or ‘FILL’.
• There must be at least two track log points stored in memory to create a TracBack route.
• If there is not enough available memory to add more waypoints and 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.)
• If the receiver is turned off or you lose satellite coverage during your trip, the TracBack route will simply draw a straight line between any point where coverage was lost and where it resumed.
• If the changes in direction and distance of your track log are complex, 30 waypoints may not be enough to accurately mark your exact path. The receiver will then assign the 30 waypoints to the most significant points of your track, and simplify segments with fewer changes in direction.
• To save a TracBack route, copy route 0 to an open storage route before activating another TracBack. Activating another TracBack or storage route will overwrite the existing TracBack route.
• Whenever a TracBack route is activated, the re­ceiver will automatically erase any temporary waypoints (‘T###’) that are not contained in routes 1-19. If there are temporary waypoints stored in routes 1-19, the receiver will create any new tem porary way points using the first three-digit num­ber available. (You can also quickly delete all tem­porary TracBack waypoints in memory by using the ‘DELETE BY SYMBOL’ method described on pg. 27.)

Navigation
Route Navigation
The last form of navigating to a destination with the GPS 12CX is by creating a user-defined route. The route navigation feature lets you plan and navigate a course from one place to another using a set of pre-defined way­points. Routes are often used when it’s not practical, safe, or possible to navigate a direct course to a particular destination (e.g., through a body of water or impassable terrain).
Waypoint 2
(”activ e to w aypo int” )
“Active Leg”
Waypoint 1
(”activ e from” waypoi nt” )
Routes are broken down and navigated in smaller segments called “legs”. The waypoint you are going to in a leg is called the “active to” waypoint and the waypoint immediately behind you is called the “active from” way­point. The line between the “active to” and the “active from” waypoint is called the “active leg”.
Whenever you activate a route with the GPS 12CX, it will automatically select the route leg closest to your position as the active leg. As you pass each waypoint in the route, the receiver will automatically sequence and select the next waypoint as the “active to” waypoint.

Routes 1-19 are used as storage routes, with route 0 always serving as the active route you are navigating. If you want to save a route that’s currently in route 0, be sure to copy it to another open route, as it will be overwritten by the next route activation.

Activating and Inverting Routes
After a route has been entered, it can be either acti­vated in sequence or inverted from the route definition page. The process of activating or inverting a stored route takes a storage route (routes 1-19) and copies it into the active route (route 0) for navigation. The storage route is no longer needed and will be retained in its original for­mat under its existing route number.
This system allows you to have an active route that you may edit during navigation and save as an entirely new route from the original. You will have to copy the active route to an unused storage route to save it, since new route or TracBack activation overwrites route 0.

304.0 kHz with a bit rate of 100 bps if no previous beacon has been tuned. (You may also enter your own frequency and bit rate if desired.) This information is used to tune/ control an optional GARMIN GBR 21 differential beacon receiver.
Note: Use the ‘RTCM/NONE’ setting if your beacon receiver does not support these software-driven controls.

Interface Setup: DGPS (continued)
To enter a DGPS beacon frequency:
1. Highlight the ‘FREQ’ field, and press
2. Enter the desired frequency, and press
3. Highlight the ‘RATE’ field, and press
4. Select the desired bit rate (bps), and press
Note: The frequency and bit rate fields are disabled
when the ‘RTCM/NONE’ option is selected.
When the GPS 12CX is receiving DGPS corrections from the GBR 21, the ‘BEACON RECVR’ section of the I/ O setup page will display the beacon frequency and sig­nal strength, as well as the distance from the beacon transmitter to your present position. At the bottom of the beacon receiver field, a status message will keep you informed of DGPS activity:
• A ‘Tuning’ message will be displayed while a beacon receiver is selecting a frequency/bit rate and waiting for signal reception.
• Once a valid beacon signal has been received, a ‘Receiving’ message will be displayed.
• If the beacon signal is received and no correction data is being received, a ‘No Data’ message will be dis­played.
• If a beacon frequency cannot be tuned and/or no signal is received, a ‘No Status’ message will be dis­played.
The message page will alert you to any problems relating to DGPS operation. You may also monitor the DGPS status from the status field on the interface page. The GPS 12CX will display one of three alert messages concerning DGPS operation:
No DGPS Position— there is not enough correction
data available to compute a DGPS position.
No RTCM Input— the beacon receiver is not properly
connected, the baud rates do not match or no signal is being provided.
RTCM Input Failed— DGPS data was being received
but has been lost.

Initializing the
Receiver
Welcome Page
Initializing Your GPS 12CX for First-Time Use
The GPS 12CX typically acquires a position fast enough that initialization is not required. However, ini­tialization may be necessary for the following:
• After memory loss
• When the receiver has been moved more than 500 miles with the power off.
Additionally, it may be necessary to initialize the unit the first time you use it, if it does not acquire a fix after the first few minutes.
The receiver is shipped from the factory in AutoLo­cate™ mode, which enables the GPS 12CX to deter­mine its location anywhere in the world. To speed up the initialization process, we recommend using the graphic initialization described below, which will usu­ally provide a fix in a few minutes.
To turn the GPS 12CX on:
1. Press the
The welcome page will be displayed while the unit conducts a self test. Once testing is complete, the wel­come page will be replaced by the Satellite Page, and the EZinit prompt may appear prompting you to select one of two initialization methods
• Select Country – allows you to initialize the receiver by selecting your present position from a list of countries in the GPS 12 CX’s internal database. This typically provides a position fix in under three minutes.
• AutolocateTM – allows the GPS 12CX to initialize itself and calculate a position fix without knowing your present position. This usually provides a fix in 3-5 minutes.
If the EZinit prompt has not automatically appeared
on the Satellite Page:
1. Press the
POWER
key until the receiver turns on .
ENTER
key.
The EZ-Init prompt will automati­cally appear if the receiver needs to be initialized. The prompt may also appear during normal use if the antenna becomes shaded.
46
Note: If the EZinit prompt ever appears after you have initialized the receiver (due to the antenna’s view of satellites being obstructed by trees, etc.), highlight the ‘NO RE-INIT’ selection with the arrow keypad and press
ENTER
.

To initialize the receiver:
1. If the ‘COUNTRY’ option is not highlighted, press the

down repeatedly to move the field highlight to
the ‘COUNTRY’ option.

to finish.
The GPS 12CX will now begin searching for the ap­propriate satellites for your location and should acquire a position in under three minutes. You can verify that you have acquired a position by watching the Satellite Page transition to the Position Page (provided you haven’t pressed any other buttons) or by looking for a ‘2D NAV’ or ‘3D NAV’ status at the top-left corner of the Satellite Page.
Initialization Troubleshooting
If you have trouble initializing the receiver or acquiring a position, check the following:
• Does the unit have a clear view of the sky?
If there are large buildings or mountains nearby, or if there is heavy tree cover, the receiver may not be re­ceiving enough satellite signals to calculate a position.
• Have you selected the right country/state/region from the EZinit list?
Check for the correct approximate lat/lon on the Position Page, or reselect the appropriate country from the list to restart the initialization.
• Have you moved more than 500 miles from the last calculated position with the receiver off?
Reinitialize the receiver, selecting the country/state/ region of your new location from the EZinit list. Your unit should now be initialized.
