5 Quic k Star t T our The Quick Start Tour will teach you the basic op- eration of your GPS 12CX. This tour assumes that none of the factory settings (units of measure, selectable fields) have been changed. If the settings have been changed the pictures and descriptions you see in the manual may not match what you see on the screen. T ur ning on th[...]

6 Using the P osition P age Walk briskly for 3 - 4 minutes and watch the position page. This is a good opportunity to compare the Com- pass Tape at the top of the page and the Track (the direc- tion 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 [...]

7 QUICK ST ART Compass Page & Cancelling a GOTO Compass P age Whenever you select a destination waypoint, the GPS 12CX provides graphic steering guidance with the Compass Page (the default navigation page).

The Compass Tape at the top of the page is a[...]

13 REFERENCE Maximum Speed & Altitude Fields Maximum Speed Field To obtain the most accurate reading of your maxi- mum speed, keep in mind that due to the sensitivity of the GPS 12CX’s antenna, your maximum speed value may include the effects of rapid movement, such as swinging your arm while holding the unit. T o reset the maximum speed fiel[...]

14 Ma p P age The Map Page shows your current position and sur- roundings, 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 way- point, and mark new waypoints while you navigate. The map displays your present position as a diamond icon, with your track [...]

T o access the user-selectable field: 1. Highlight ‘ETE’, and press ENTER . 2. Use the keypad to scroll through the possible options. The foll[...]

21 Using the Compass P a ge 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 way- point are displayed at the top of the page, below the destina[...]

22 Using the Highw a y P age 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 dis- tance 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 s[...]

23 Cr ea ting W a ypoints The GPS 12CX allows you to store up to 1000 posi- tions as waypoints. A waypoint can be entered by taking an instant electronic fix, by manually entering coordi- nates, by using the bearing and distance to a known position or by marking a position on the map page. Marking a Position The GPS 12CX can instantly capture and s[...]

24 W a ypoint Comments Each waypoint stored in the GPS 12CX has a user defined 16-character comment field.

29 Cancelling an active GOTO Man Overboard Function Activating a Direct GOTO Selecting a GOTO Destination The GPS 12CX provides four ways to navigate to a destination: GOTO, MOB, TracBack, and Route naviga- tion. The most basic method of selecting a destination is the GOTO function, which lets you choose any stored waypoint as the destination and q[...]

30 Clearing the Track Log Activating a TracBack Route T r acBac k Na vig a tion 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 [...]

31 Activating a TracBack will create a route base on your current track log. ‘T’ waypoints and symbols will be added to the waypoint list and displayed on the map for easy iden- tification. The TracBack will be- come the ‘Active Route’ and dis- played on the active route page. To cancel an active TracBack, high- light the ‘CLR’ field at[...]

32 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 way- points. Routes are often used when it’s not practical, safe, or possible to navigate a direct course to a[...]
