GPSmap 76C

Introduction

MAP DATA INFORMATION: One of the goals of Garmin is to provide customers with the most complete and accurate cartography that is available to us at a reasonable cost. We use a combination of governmental and private data sources, which we identify as required in product literature and copyright messages displayed to the consumer. Virtually all data sources contain inaccurate or incomplete data to some degree. This is particularly true outside the United States, where complete and accurate digital data is either not available or prohibitively expensive.

WARNING: The Global Positioning System (GPS) is operated by the United States government, which is solely responsible for its accuracy and maintenance. The system is subject to changes which could affect the accuracy and performance of all GPS equipment. Although the Garmin GPSmap 76C is a precision electronic NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted and, therefore, become unsafe.

WARNING: This product, its packaging, and its components contain chemicals known to the State of California to cause cancer, birth defects, or reproductive harm. This Notice is being provided in accordance with California’s Proposition 65. If you have any questions or would like additional information, please refer to our web site at http://www.garmin.com/ prop65.

Getting Started

Initialization & the Satellite Page

The GPSmap 76C locates satellites above its position

Heading Bug

direction of movement.

Options

Satellite Page Acquiring Satellite Signals

Starting Up the GPS Receiver

When you turn on the GPSmap 76C, the GPS receiver begins to search for satellites in order to determine (ﬁ x) its location. This process is called “initialization” and can take from 5 to 15 minutes the ﬁ rst time you use your unit. Thereafter, if you haven’t moved more than 600 miles from your original location, it takes only seconds to minutes. In order to receive satellite signals, you must be outdoors and have a clear view of the sky. Satellite signals cannot pass through solid materials (except glass) or dense overhead tree cover. To shorten the time required for initialization, select “New Location” from the options menu, then use the Map Page to determine your general location

so the

GPSmap 76C

can search

for those satellites above you.

o initialize your GPSmap 76C:

1. Press and release the POWER key to turn on the unit.

2. Observe the “Power On” Page followed by the Satellite Page.

3. While the GPS receiver is searching for the satellite signals, a “Locating Satellites” message is replaced by an “Acquiring

Satellites” message until enough signals are acquired to ﬁ x its location. If the unit cannot get a satellite ﬁ x, a list of solutions appears. Highlight the appropriate solution and press ENTER.

You can also observe a sky view array of the satellites overhead with your position centered in the array. The outer circle represents the horizon and the inner circle a position 45o from the horizon. The numbers displayed indicate the number assigned to each satellite. A bar graph at the bottom of the page displays the strength of signals from each satellite.

GPSmap 76C

Getting Started

4. When the receiver has signals from at least three satellites, the display at the top of the page will change to indicate position accuracy and location coordinates. The Status Bar at the the display indicates the GPS status and status of other

top of

features.

If, for any reason, you have difﬁ culty initializing your GPSmap 76C, the solution could be as simple as moving slightly to avoid objects that are blocking or deﬂ ecting the satellite signals.

5. Press and release the PAGE key until the Map Page is displayed. You are now ready to begin GPS aided navigation.

Active Navigation is supported by three of the Main Pages:

The Map Page graphically shows you map details, your current location, marks your route to a destination with a route line, and leaves a trail (track log) of where you’ve been.

The Compass Page indicates direction to go and direction of travel.

The Trip Computer Page records and displays travel data.

There are three methods of navigating to a destination when using the GPSmap 76C’, each graphically displayed on the Map Page.

Go To -

A direct path to a selected destination (waypoint, city, address, etc.).

Track - A previous path of travel that has been stored (logged) in the

GPSmap 76C.

A Track allows you to repeat or retrace a path.

Route - A path to a destination consisting of intermediate stops along

the way (waypoints, cities, exits, points of interest, intersections, etc.).

Refer to the sections on Tracks, Routes and Waypoints for details.

Status Bar, Backlighting and On-Screen Messages

At the top of each page, a Status Bar (which is always displayed)

provides current status information for several unit features.

• Power to the unit is provided by either the batteries or from an auxiliary source (AC or DC Adapter). The Battery Power icon displays the remaining power as the battery becomes depleted.

• Satellite signal status is shown when searching for (acquiring) satellites, when a two-dimensional ﬁ x is attained and when four or more satellites have been received (three dimensional ﬁ x).

• Backlighting is Off when you power up the unit. When On, it uses a signiﬁ cant amount of battery power. This icon displays when the backlight is functioning.

• Alarm Clock: this icon displays whenever the alarm is

set.

• USB cable connection displays when the unit is in communi cation with a PC Universal Serial Bus.

You may want to adjust the backlight level by pressing down on the POWER key and releasing. Then tap the POWER key or ROCKER key Up/Down arrows to cycle through the levels of backlight adjustment. See page 48 for information on changing the display colors and backlight timeout and brightness levels.

Whenever a signiﬁ cant event in the operation of the unit occurs, an on-screen message displays to advise you of the occurrence. In each case the condition is described and, often, a remedy provided. Pressing the ENTER key acknowledges the message and closes the window.

Detailed Mapping

Using the Map Page

The Map Page is the primary navigation feature of the GPSmap 76C. The Map Page displays a detailed map of the area surrounding your current location. It allows you to pan the map with the ROCKER key as well as view your progress when navigating. When in the “Track Up” mode (oriented in the direction of travel), a north reference arrow appears at the top left corner to orient the map. When in the “North Up” mode the map is oriented like a paper map. When you activate the

Track Log feature, your path of movement is indicated by a dotted line. The map display can be changed to “Night” mode for easier viewing in dim light. The factory set default automatically changes the display at sunrise and sunset.

The map also displays geographic details such as rivers, lakes, highways, towns and Tide Prediction Stations contained in the basemaps included with the unit. The maps to the left show a higher level of detail than the basemaps provided with the unit (i.e. residential streets, parks, etc.) because Garmin MapSource® detailed mapping data has been downloaded from a CD-ROM program.

You can use the Map Page to:

• Determine your current location and progress while moving.

• Select and save a map point as a waypoint.

• Locate and navigate to map items by following a Route displayed on the map.

• Customize the map display to your requirements.

GPSmap 76C

Using Map Page Features

Use the Zoom In and Out buttons to change the map scale in order to show more map area with less detail or less map area with more detail. Press and hold to Zoom the map scale rapidly.

The map scale in the lower left hand side of the display is shown in units of measurement selected in the “Units” ﬁ eld of the Unit Setup Page (not to be confused with the Map Setup Page). If you zoom in so far that the resolution of the map data is exceeded and the appearance of the map is no longer accurate, the word, “ overzoom” displays just below the map scale. When using MapSource detailed maps, “mapsource” appears below the scale.

In many instances the map displays an “Accuracy Circle” surrounding the “Position Icon.” The GPSmap 76C uses both map resolution and GPS accuracy in deﬁ ning your location to a point within the circle. The smaller the circle, the more accurate your location.

When using the “Pan Map” feature, a small outline arrow (Panning Arrow) can be moved about the page to highlight and identify map items or to scroll the map to view areas not shown on the display screen. If there are multiple map items under the Panning Arrow. a list of those items displays with the item highlighted on the map, also highlighted on the list.

Using the Compass Page

The Compass Page is your guide to accurate and efficient navigation. It

uses traditional navigation displays to provide navigation information.

Whenever navigation is in progress, the Compass Page provides navigation data and directions. It uses a graphic compass display and a bearing pointer along with digital data fields to display information such as current speed, distance to the next point on the route, estimated arrival time, etc. You can choose from three or four data fields and select the type of data displayed in each from a list of options.

When moving, the rotating graphic compass indicates the direction you are heading. The Bearing Pointer indicates the direction (bearing) to your destination, relative to your current heading direction. The compass dial and bearing pointer work independently to show your direction of movement and the direction to your destination. You can choose between a Bearing Pointer or a Course Pointer for guidance.

The compass does not function as a magnetic compass when you are stationary. However when you move, the dial rotates to keep you oriented in relation to North. This is especially helpful when using a paper map in conjunction with your unit for navigation.

o use the Compass Page Options:

Press the MENU key to display the Options Menu.

2. The ﬁ rst option is “Stop Navigation” which can be highlighted and activated by pressing ENTER to stop navigating.

3. The second option is “Course Pointer” or “Bearing Pointer”.

The Bearing Pointer and Compass Ring work independently of the direction of your movement and the direction to your destination. The Bearing Pointer always points directly to the destination, no matter what your current location might be.

For example: if the arrow is pointing straight up, you are going directly to your destination. If it points any direction other than up, turn towards that direction until the arrow is pointing up and then continue in that direction. If you are using the ‘Course Pointer’ option instead and you drift away from the line of travel to your destination, the Course Deviation Indicator (CDI) provides graphic indication of drift (right or left) and displays the distance off course.

4. The third option is “Data Fields”. Highlight the data ﬁ elds option and press ENTER to display the “Show: 3 Data Fields or 4 Data Fields” options. Highlight your selection and press ENTER.

5. The next option is “Change Data Fields” which allows you to determine what data is displayed in the ﬁ elds. When you select this option, the topic of the ﬁ rst data ﬁ eld on the page will be highlighted. When you press ENTER, a list of data options will appear. Refer to page 11 for details on changing data ﬁ elds.

Creating and Using a Route

Route navigation allows you to create a sequence of intermediate waypoints which lead you to your ﬁ nal destination. The GPSmap 76C stores 50 routes, with up to 250 waypoints each. A route can be created and modiﬁ ed from the Routes Page, and waypoints can be added to a route from the Find Menu. More complex routes can be created using a PC and MapSource mapping programs and then transferred to the unit memory. Auto-Routes which are generated when you select “Go To” for a Find item or waypoint cannot be saved.

Saved routes with more than 50

waypoints cannot be navigated using the “Follow Roads” option.

To create and save a route:

1. Access the “Routes” page from the Main Menu. The page has a “New” button, an “Active” button and a list of saved routes.

2. Use the ROCKER key to highlight the “New” button and press ENTER to display the route Setup Page.

3. With an empty row (dashed) in the route list highlighted, press ENTER to display the Find Menu.

4. Use the Find Menu to select a route waypoint from one of the Find Menu groups and display the Information Page for the selected waypoint, city, exit, point of interest, etc. Highlight the on-screen “Use” button and press ENTER to place it on the Route Waypoint List.

5. To add more waypoints to the route, repeat the process in Steps 3 and 4. You can rename the route if desired.

6. Press QUIT to save it to the Saved Routes list, or highlight the “Navigate” button and press ENTER to navigate.

Methods of navigating to a destination:

• When you activate the “Go To” button on the Information Page for a User Waypoint or other Find Menu items, the GPSmap 76C creates a straight path (point to point) from your current location to that location.

• When you press the “Navigate” button on a Route page the GPSmap 76C creates a route composed of several User Waypoints or Find Menu items, with the last being your destination. It navigates directly from point to point. Before each turn in the route a turn page displays a guidance message and graphic of the turn. You can view the turns at any time by pressing the ROCKER key Up or Down arrows while the route is active.

• These two navigation methods change when you select the “Follow Roads” option from the Routing Setup Page. Both Go To navigation and point to point routing become routes that allow you to navigate using roads.

The routes use existing roadways (either those in the basemap or

from downloaded detail mapping) to automatically calculate a route to your destination. Turns on roadways are added to the active route page and will be preceded by a guidance message with graphic display of the turn.

If there are not enough roads at your location to calculate a route, a

message will display to advise you.

Virtua Maze

This GPS game creates a virtual maze on the screen. You are placed at a central position in the maze and must explore the maze collecting flags. The lower right corner of the screen tells you how many flags remain. The lower left corner is a timer displaying the elapsed time. The Difficulty Lever determines how much of the maze you can see at one time. Viewing less of the maze makes the game more difficult.

HINT: Pressing the ENTER key and selecting “Cheat On” will enable a “cheat mode.” Enabling this mode will penalize you by five minutes and count seconds by 10 instead of 2. Turn the cheat mode Off by pressing the ENTER key.

Geko Smak

Geko Smak is a GPS based game that features you as the player piece. In measured rhythm, Gekos will appear on the screen. Before the Geko disappears, move toward the Geko and press the ENTER key to smack the Geko with a hammer. If you get the Geko, an “!” mark displays above the hammer, if not, just a hammer displays momentarily.

Field size choices are small, medium and large, with small fields being roughly 20 yards by 30 yards and large fields being 60 yards by 90 yards (about the size of an American football field).

The difficulty levels are: Easy, Normal and Hard. These levels determine how often Gekos appear. The pace quickens and values vary as difficulty levels increase.

Nibbons

In this GPS game, you must walk around the board collecting the flags as they appear. As you walk, your “tail” will grow. You may travel anywhere on the screen but you cannot walk on your tail, or you will lose a life. As an added challenge, you must also avoid the Skulls that chase after you.

Gekoids

This GPS game, which can be played without GPS on, is all about blasting gekoids. The catch is, you are the ship and you can survive only when you avoid getting hit. Before you begin to play, make certain to make your game settings. Orient Map “Northwards” rotates your ship in the center of the map. The map is stationary and north is always up. Orient Map “Ship Up” rotates the virtual world around your ship. Your ship always points Up.

Press the ENTER key to start and blast away!

IMPORTANT WARNING: When playing any of the virtual games (where you are moving about on a real playing field), use reasonable and prudent caution in selecting an area free of hazards such a holes, obstructions or proximity to vehicular traffic. Playing these games may distract your attention from observing objects in your path.

Transferring MapSource Map Data

If you have purchased a Garmin MapSource CD-ROM mapping program you may want to transfer detailed map data before beginning use to provide your unit with maximum Find features and mapping capability. The GPSmap 76C accepts up to 115 MB of map data from most MapSource products. It is not possible to transfer 3rd party maps into Garmin products.

You cannot view multiple types of MapSource data in the same location at the same time (one displays over the other). When navigating a City Select map area, for example, and enter another map covering the same area, the map higher in the MapSource hierarchy displays over the other.

Maps that are at the top of the hierarchy will display over any other map information. Because new maps are constantly being released, consult your Garmin Dealer or the Garmin website to determine the order of hierarchy.

Map data transfer requires the use of a PC, a Garmin MapSource CD-ROM, and the Universal Service Bus (USB) cable supplied with this unit. Follow detailed instructions for data transfer in the MapSource User’s Manual. Note that downloading maps overwrites any maps already downloaded to the unit. This includes the Marine Points of Interest database provided with the GPSmap 76C.

It is also important to note that certain features contained in the GPSmap 76C are not enabled unless you are using mapping data they are designed to support, such as many of the Find Features and DEM Elevation Proﬁ les. Visit the Garmin website for details on all of the maps you can use with the GPSmap 76C.

What are Map Datums, and which should I use?

A datum is a mathematical model of the Earth which approximates the shape of the Earth, and enables calculations to be carried out in a consistent and accurate manner. The datum is physically represented by a framework of ground monuments (i.e. trig. stations) whose positions have been accurately measured and calculated on this reference surface. Lines of latitude and longitude on a map or chart are referenced to a specific map datum. Every chart has a map datum reference and the GPSmap 76C can be set to match most of those commonly used.

If you are navigating and comparing the GPS coordinates to a map, chart or other reference, the map datum in the GPS unit should be set to the same datum as the map or chart to insure the most accurate navigation.

GPSmap 76C

Appendix

Map Datums and Position Formats

What is a Position Format, and which should I use?

Your current location can be viewed on the GPS in the form of coordinates. Since different maps and charts use different location formats, Garmin GPS units allow you to choose the correct coordinate system for the type of map you are using. The most common format is latitude and longitude, which is utilized by all Garmin units. On most models, you may choose to change the position format to use with other coordinate systems. UTM/UPS (Universal Transverse Mercator/Universal Polar Stereographic) are easy-to-use metric grids that are found on most USGS topographic quadrangle maps. Several other grids, including a user-deﬁ nable grid (for the advanced user), may also be selected.

Map Datums are based on a

mathematical model of the Earth.

6. When done, highlight the “Save” button and press ENTER.

If the active GRI Chain, secondary stations, or offsets have been changed since the waypoint was created, the waypoint now references the active GRI-chain and secondary stations and adjust the TD coordinates accordingly. Remember that the GPSmap 76C is not relying on the LORAN signal for navigation and actually converts the TD coordinate to a useful LAT/LON coordinate before storing the waypoint to memory or using it for navigation. Because of this, the unit can navigate to a TD coordinate anywhere in the world.

You must know your GRI chain number and secondary stations to create a LORAN TD position. For more information please read our LORAN TD Position Format Handbook, available at the Garmin Web site, at www.garmin.com/support/userManual.html.

Appendix

What is WAAS?

The Wide Area Augmentation System (WAAS) is an FAA funded service to improve the overall integrity of the GPS signal for users in North America. WAAS is just one service provider that adheres to the MOPS (Minimum Operational Performance Standard) for Satellite Based Augmentation Systems (SBAS). Eventually there will be several services of worldwide geostationary communication satellites that broadcast integrity information and differential correction data as transmitted by ground reference stations.

At this time WAAS is still in the developmental stage with a goal of providing reliable signals with an accuracy of 7 meters (21-22 feet) both horizontally and vertically 95% of the time. Current tests have shown the actual accuracy to be on the order of 2-3 meters (7-10 feet). This accuracy is comparable to DGPS (as explained below), but without the need for a separate beacon receiver. Since all SBAS systems use the same receiver frequency, any SBAS system should be capable of providing your GPS unit with increased accuracy at any location in the world when others under development reach operational status.

In addition to satellites in orbit over the Earth, ground based reference stations must also be in place near the region you are located. Enabling WAAS in regions that are not supported by ground stations, which correct position data, typically, does not improve accuracy even when receiving signals from an SBAS satellite. In fact it can degrade the accuracy to less than that provided by GPS satellites alone. For this reason, your Garmin GPS receiver, when in the “WAAS Enabled” mode, selects the method that achieves the best accuracy. To enable/disable WAAS, refer to the System Setup Page of your unit. For more information, go to http://gps.faa.gov/Programs/WAAS/waas.htm.

What is Differential GPS (DGPS)?

The U.S. and Canadian governments (among others) have set up Differential GPS (DGPS) beacon stations along seacoasts and inland waterways to transmit correction signals. The DGPS system is available for use without fee.

Refer to the U.S. Coast Guard’s web site: http://www.navcen.uscg.gov/ for locations and the status of the differential beacon sites. Using DGPS requires interfacing of your unit to additional equipment in the form of a beacon receiver compatible with the RTCM format sentences supported by your Garmin GPS. Refer to the section titled “Interface Setup.”
