Stored in the permanent memory of each unit is a basic background map of the entire world.
Another portion of the GlobalMap c's onboard memory is devoted to recording GPS navigation infor- mation, which includes waypoints, event marker icons, trails and routes. Page 13 A minimum of three satellites are required to determine a 2D fix. The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation your height above sea level — also called altitude. You'll find that using your GPS receiver is both easy and amazingly accurate.
Page Menu Commands Menu Commands A menu command or a menu option will appear in small capital letters, in a bold sans serif type like this: you are to select this command or option from a menu or take an action of some kind with the menu item. Text that you may need to enter or file names you need to select are show in italic type, such as trail name.
Page 16 Notes Page Power Connections You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, connect it to the end of the extension cable. To connect it to the unit, insert the cable's plug into the Network socket on the back of the unit or a double T connector attached to the unit.
The bare ends on any unused wires could cause an electrical short if left exposed. To prevent this, you should cover the individual wire ends — either by capping them with wire nuts, wrapping them with electrical tape or both.
Page Power Diagram A If possible, keep the power cable away from other boat wiring, espe- cially the engine's wires. This will provide the best isolation from elec- trical noise. If the cable is not long enough, splice 18 gauge wire onto it. The display power cable has three wires, white, red and black. If you have a network that is already powered, see diagram To unit All unused Data or NMEA power wires should be capped with wire nuts and electrical tape to prevent shorts.
The NMEA Power cable's black and shield wires should both be attached to the negative — terminal. Page Nmea Cable Connections Your unit does not use the blue wire.

Page 26 Front Install the gimbal bracket. Orient the bracket so the arms slope to- Drill a 1-inch The best location for this hole is immediately under the gimbal bracket location.
This way, the bracket can be installed so that it covers the hole, holds the cables in position and results in a neat installation. Page 27 In-dash mounting template for the GlobalMap c, showing dimensions. NOTE: The figure above is not printed to scale.
The power pack and the magnet-equipped antenna module expand the uses for your GPS unit. The portable power pack makes it easy to transfer your unit from a boat to a car, recreational vehicle, airplane or other vehicle without drilling and mounting a second bracket. Open the card compartment door by unscrewing the thumb screw. The screw should only be finger tight. If it was over-tightened, use a thumbnail, a coin or a screwdriver to open the door. Just press a finger against the label of the MMC and drag it from the slot.
Page Face Cover Face Cover Your unit comes with a white protective cover that snaps on and off the front of the unit. This cover is intended for use when your unit and the vehicle it's mounted in are idle. WARNING: When the unit is mounted in an unprotected area, such as an open boat cockpit, the protective face cover must be removed when the vehicle is moving at high speed.
Each page represents one of the unit's major operation modes. MENU — Press this key to show the menus and submenus, which allow you to select a command or adjust a feature. This also accesses search functions for streets, intersections, addresses and highway exits.
Page 33 Point of Interest or map cursor location; or after you reach the end of a route or trail. System Setup command: sets general configuration options. Pages The unit has four Pages that represent the major operating modes.
Page 35 North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north. The GPS receiver is tracking satellites that are in bold type.
The right figure shows the subcategory list under the GPS Data category. When Position Error is on, it will show you the expected error from a benchmark location.
In other words, if the Position Error box shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. Page 38 When navigating to a waypoint your ground speed, track, distance and bearing to waypoint, and course are all shown digitally on this screen. NOTE: Remember, when the Speed, Track and Position information dis- plays are flashing, satellite lock has not been achieved and no posi- tion fix has been determined.

The cross track error range is shown on the compass rose as a wide, white, corridor enclosing the course line.
Page Map Page The Navigation Page has its own menu, which is used for some ad- vanced functions and for setting various options. Options and setup are discussed in Sec. Page Background Map Vs.
Mapcreate Map Content If you're using only the factory-loaded background map, the maximum zoom range for showing additional map detail is 20 miles. You can con- tinue to zoom in closer, but the map will be enlarged without revealing more map content except for a few major city streets.
Page 42 What's more important is the large scale map detail that allows your GPS unit to show a higher level of position accuracy. For example, the background map would show you the general outline and approximate shape of a coastline or water body, but the higher de- tail in MapCreate shows the shoreline completely and accurately finer detail. Page Resize Window Command The Map Page has its own menu, which is used for several functions and for setting various options. Page 44 Pages Menu with Two Maps option selected, at left.
The Resize Win- dow feature was used to make the maps vertical. Map Page with two horizontal map windows, at right. The bottom map is the active map. Resize Window is a useful feature for pages that have two major win- dows.
Press flashing arrows. To change the window size again or revert back to the original dis- play, just follow the steps above.
Most dual-window displays use half the screen for each window by default. To stop scrolling and return to current position on map, press 6. Set a waypoint Wpt at your current position so you can navi- gate back here: press 7. This keeps your current location roughly centered on-screen. You can manually pan or scroll the map north, south, east or west by using the arrow keys, which launch the cross-hair map cursor. This allows you to look at map places other than your current position.
Page Searching Searching Now that you've seen how the unit can find where you are, let's search for something somewhere else. Searching is one of the most powerful features in the Lowrance GPS product line. In this example, we'll look for the nearest fast-food restaurant. For more information on different types of searches, refer to Sec.
Page 49 POI information screen on fast food restaurant nearest this position. Page Set A Waypoint Set a Waypoint A waypoint is an electronic "address," based on the latitude and longi- tude of a position on the earth. A waypoint represents a location, spot or destination that can be stored in memory, then recalled and used later for navigation purposes. Page 51 Create Waypoint at Current Position While you are traveling, press automatically given a name with a sequential number, such as "way- point Step 1.
Step 3. Sequence for setting a waypoint. Page Navigate To A Waypoint Navigate to a Waypoint You can select any waypoint visible on the Map Page with the cursor, then use the Navigate to Cursor command we'll describe how later in this section. However, you can avoid scrolling the map to pick your waypoint if you use the Find Waypoint commands. Page Navigate Back To Mob Waypoint To activate it, press the tion at the time these keys are pressed is used as the man overboard position.
Caution: Saving a new "Man Overboard" waypoint will overwrite and erase the previous "Man Overboard" waypoint. Page 54 2. Center the cursor over the location to select it. See the example in the following figure. Many map items such as waypoints, Points of In- terest, towns, etc.
Other features, such as a river or a street intersection will not appear "highlighted," Page 56 To Save a Trail 1. The Trails Menu, at left. The arrow to the right of Trail 2 indicates the trail is "active" and the check to the left indicates the trail is visible on the map display. Page Visual Trailing The other two methods provide a full range of navigation data and work with both the Map Page and Navigation Page.
The only difference between them is "navigating a trail" follows a trail forward from start to end while "backtracking" follows a trail in reverse from end to start. When hiking at walking speed with a hand-held GPS, we often just use visual back trailing because it is a bit better at following each little Page 59 Figure 1. Figure 2.
