(Zooms in) PAGE Key The PAGE key selects the main pages in sequence and returns display from a submenu page. Getting Started Keypad Usage OUT QUIT Key The QUIT key returns the display to the previous page and, when entering data, it restores the previous value (cancels data entry).
Getting Started Selecting Options The GPSMAP 178C Sounder’s advanced keypad system is designed to allow for fast, convenient selection of navigation options and data entry. The Getting Started Tour introduces you to the keypad and provides a ‘hands-on’ lesson in using the GPSMAP 178C Sounder. We strongly encourage you to follow the Getting Started tour before using your unit for actual navigation.
Naming a waypoint or placing any sort of data that has not been predefined requires the use of both the ARROW KEYPAD and the ENTER/MARK key. Getting Started Entering Data To enter a name or number in a data field: 1. Once you have accessed a page with programmable data fields (e.g. ‘ Waypoint Edit’) you can use the ARROW KEYPAD to move the cursor (Highlight) to fields on the page. Use the UP/DOWN arrows to move up or down and the LEFT/RIGHT arrows to move sideways. 2.
Getting Started Initializing the Receiver/ Power On Initializing the Receiver The first time you power up your GPSMAP 178C Sounder, the receiver must be given an opportunity to collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 178C Sounder is shipped from the factory in AutoLocate mode, which allows the receiver to “find itself” anywhere in the world.
To graphically initialize the GPSMAP 178C Sounder: 1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until the ‘GPS’ tab is highlighted, then press the MENU key once. Getting Started Initializing the Receiver 2. Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER to initialize the receiver from the map. The Initialize Position Page appears, prompting you to select your approximate location with the map cursor. 3.
Getting Started Tour/Backlighting GPSMAP 178C Sounder Getting Started Tour The Garmin GPSMAP 178C Sounder is a powerful electronic navigation system that provides detailed map coverage and convenient control of many advanced features right from the screen display. This tour is designed to take you through the basic pages and functions of the system using the simulator mode.
Each page of the GPSMAP 178C Sounder’s system also features an options page, which gives you access to other functions and features that relate to the specific page you are viewing. To get a feel for how the option pages work, let’s put the GPSMAP 178C Sounder into simulator mode. Getting Started Simulator Mode To activate the simulator mode: 1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until the ‘GPS’ tab is highlighted, then press the MENU key once. 2.
Main Pages Getting Started Main Pages/ Map Page The Map Page is one of six main pages used in the GPSMAP 178C Sounder’s system. The six main pages are the Map Page, Map/Sonar Split Page, Sonar Page, Compass Page, Highway Page, and Active Route Page. All pages are linked together in a simple chain, which allows you to scroll through the pages in either direction using the PAGE and QUIT keys.
Using the Map Cursor Working from the Map Page is a simple process that centers around the use of the cursor. Controlled by the ARROW KEYPAD, the cursor is an important tool that can be used to pan to other map locations, mark and edit waypoints and routes, and review position data of on-screen map items and waypoints. Getting Started Map Cursor To get a feel for using the Map Page and using the cursor, try the following exercise: 1. Use the IN/OUT keys to set the map scale to the 50 nm setting.
Getting Started Marking Waypoints To mark your present position: 1. Hold down the ENTER/MARK key until the ‘New Waypoint’ window appears then release the key. The window shows a default three-digit waypoint name/number (001), symbol (dot), and position. You can leave the name as the auto-assigned number, but for this exercise, lets change the name to ‘DOCK’. 2. Use the ARROW KEYPAD to highlight the waypoint name field (001) and press ENTER/MARK. You see that just the first ‘0’ is now highlighted. 3.
Going to a Destination GPS is all about marking positions as waypoints and navigating to them using the receiver’s steering guidance and map displays. We’ve already seen how to use the ENTER/MARK key to store your present position, so it’s time to move on to the fun part—going to a destination. Getting Started Using the NAV Key The NAV/MOB key, located on the keypad above the QUIT key, is the primary tool used to select a destination waypoint, TracBack, or a route to navigate.
Getting Started Simulated Tour To activate the practice route stored in memory for navigation: 1. Press NAV. The option list page appears. (If you were selecting a single waypoint to navigate to rather than a route, you could highlight the waypoint on the map, press NAV and then press ENTER.) 2. Use the ARROW KEYPAD to highlight the ‘Follow Route’ option. Press ENTER to confirm. 3. The Select Route page appears, with the ‘GPSMAP TOUR’ route highlighted. 4.
You’ll now have a clearer picture of the route you are navigating. Keep in mind that when you exceed the usable range of the built-in database or the optional MapSource or BlueChart data in use, the range field displays ‘overzoom’ to indicate that you should exercise extreme caution using the map data. Press the ZOOM IN key to zoom into the 2 nm scale. Now that you’ve zoomed in a little closer to your route, you can pan ahead of your vessel with the cursor to review map items and create on-screen waypoints.
Map/Sonar Split Page Getting Started The Map/Sonar Split Page combines the Map Page on the left half with the Sonar Page on the right by default. You may adjust the size of the split (pg 32). Press PAGE key to proceed to the Sonar Page.
Using the Adjustment Menu The Adjustment Menu allows direct access to the settings and features most commonly used on the Sonar Page. There are 10 main adjustment options available: Range, Zoom, View/Span, Gain, Target Level, Whiteline, Frequency, Depth Line, Noise Reject, and Scroll. The currently selected option appears in the upper left of the display with up and down arrows on either side of the option name. Getting Started Sonar Page To select an adjustment option from the Sonar Page: 1.

WAAS Capability The GPSMAP 178C is capable of receiving WAAS (Wide Area Augmentation System) satellite signals. WAAS is an FAA (Federal Aviation Administration) funded project to improve the overall accuracy and integrity of the GPS signal for aviation use, but land/sea based users may also benefit from this system. At this time, the system is still in the development stage and is not fully operational. There are currently two WAAS satellites that can be received in the U.S.A.
Reference Main Menu: GPS Tab When the GPSMAP 178C is using a differential correction signal (either WAAS or DGPS), a “D” is displayed at the bottom of the signal strength indicator bars for the satellites that are corrected. 70 GPSMAP178CManual.indd 70 The status field shows one of the following conditions: • Looking For Satellites – the receiver is looking for any satellites. • AutoLocate – the receiver is looking for any satellite whose almanac has been collected.
The Differential SNR (Signal to Noise Ratio) indicates, on a scale to 0-30db with 30db being the best, the strength of the DGPS signal being received. The SNR depends upon the mounting of your DGPS receiver and the distance from the DGPS transmitting station. The GPS Info tab features an options menu that provides access to functions and features relating to the GPS Info display.
Reference Tide Tab— shows a graphical chart that displays tide station information in a 24-hour span starting at midnight station time. You can choose from different dates and over 3000 tide stations around the USA coastline, Alaska, Hawaii, western Canada and several of the Caribbean islands.

Reference Main Menu: Track Tab Saved Submenu Tab— manages a list of any saved track logs, allows TracBack activation, map display of saved logs. The active log stores up to approximately 10,000 track log points, based upon the criteria specified in the Track settings. Up to 15 track logs may be saved in memory, with up to 700 track log points in each saved log.
DSC Tab— allows to control and set up DSC (Digital Selective Calling) features on the unit. What is Digital selective calling (DSC)? Digital Selective Calling (DSC) uses marine VHF radio and Global Positioning System (GPS) technologies to transmit and receive location information. DSC is used by mariners to assist them in two major areas: Distress Calls and Position Reporting.
Reference Main Menu: DSC Tab 78 GPSMAP178CManual.indd 78 HOW ARE MMSI ASSIGNMENTS OBTAINED? Non-commercial users (e.g. recreational users who remain in domestic waters and only carry VHF, EPIRB (Emergency Position Indicating Radio Beacons), and Radar) are not required to have a FCC ship station license. The FCC and Coast Guard have authorized some second and third party vendors to assign MMSI numbers. This service is limited to registering recreational vessels only.
MMSI number attached to the call (if you have DSC support). Any DSC-equipped mariner (on sea or land) within range can receive the call. When the Garmin GPSMAP 178C is connected to a VHF with DSC support, the GPS unit displays a Call List, Log, and a Directory available to store incoming information received from another user’s DSC capable VHF/GPS combination. Basic wiring is required for the Garmin unit and VHF radio to send and receive NMEA data from each other (pg.96).
Reference Main Menu: DSC Tab DSC Call List The DSC Call List displays the current calls received. The GPS can manage up to 50 calls. When ‘calls’ are received, they are updated constantly to give the most current information, even if the unit is left unattended. Any entry from the Call List can be selected to show an Entry Review. DSC Log When DSC calls are received, they are automatically stored in the Log, with the latest call at the top. The unit may store up to 100 logs.
There are two ways to add a new entry into the directory. Reference To add a new Directory entry: 1. Press Menu, then highlight ‘New Item’ and press ENTER. Main Menu: DSC Tab 2. Or, with the Directory Tab highlighted press the Arrow Keypad DOWN, highlight an empty field and press ENTER to access the New Directory Item window. The New Directory Item window allows you to input information of a known contact. To add the MMSI number, Name, or Comment: 1.
Reference Main Menu: DSC/Card Tabs A user also has the ability to simulate a Distress Call or a Position Report on this page. This is helpful for practice before connecting to the real system. The Distress Call simulator also helps to check if alarms are working properly. To run a simulation: 1. Place the chartplotter into simulation (see pg. 7). 2. From the Main Menu, select the DSC tab, then highlight the Setup tab. 3. Highlight which simulation you wish to run and press ENTER.

Appendix A Antenna Installation Installing the GPSMAP 178C The GPSMAP 178C must be properly installed according to the following instructions to get the best possible performance. To complete the installation, you’ll need the appropriate fasteners and a 1” x 14-thread marine antenna mount available at most marine dealers. (If you have a GPSMAP 178C with an internal antenna, skip to the next page.) When in doubt, seek professional assistance.
Mounting the GPSMAP 178C Unit The GPSMAP 178C’s compact, waterproof case is suitable for mounting in exposed locations or at the nav station. The unit comes with a gimbal bracket that can be used for surface or overhead mounting. When choosing a location for the display unit, make sure you consider the following conditions: • There should be at least a 3” (5 cm) clearance behind the case to allow connection of the antenna (external antenna only), power/data cables.
Appendix A Unit Installation Installing the Unit on the Mounting Bracket 1. Align the slot on the back of the unit with the long mounting knob and slide in place. It may be necessary to adjust the long mounting knob to spread the bracket arms apart. (Turn counter-clockwise to widen the bracket arms, clockwise to tighten.) 2. Adjust the unit angle and tighten the long mounting knob until snug. 3. To tilt the unit, loosen the long mounting knob on the right side of the bracket assembly. 4.
Flush Mounting the GPSMAP 178C External Antenna Unit The GPSMAP 178C External Antenna only can be flush mounted on a flat panel. When flush mounting the GPSMAP 178C, be sure to choose an appropriately sized location for the unit. Check that all cables reach the unit mounting location before beginning installation. Use the Flush Mount Template provided in the box to determine a location. Always wear safety goggles, ear protection, and a dust mask when drilling, cutting or sanding.
Appendix A Wiring and Interfacing You can download a copy of Garmin's proprietary communication protocol from the Help and Support section of our web site at www.garmin.com. Connecting the Power/Data Cable The power/data cable connects the GPSMAP 178C to 10-35 volt DC system and provides interface capabilities for connecting external devices. The color code in the diagram below indicates the appropriate harness connections.
Transducers The transducer acts as the eyes and ears of your new sonar. Proper transducer selection and installation are critical to the operation of your unit. The transducer transmits sound waves toward the bottom in a cone shape. The larger the cone angle, the larger the coverage area at a given depth. Appendix A Selecting a Transducer A wide cone angle transducer works best in shallow water. The wide cone angle provides a large coverage area, but at a decreased bottom resolution.
Appendix A Mounting the Transducer , DO NOT mount the transducer behind strakes, struts, fittings, water intake or discharge ports, or anything that creates air bubbles or causes the water to become turbulent. It is important that the transducer be in clean (non-turbulent) water for optimal performance. Proper transducer installation is key to getting the best performance from your new unit. If the transducer lead is too short, extension cables are available from your Garmin dealer.
To avoid drilling a hole to mount a thru-hull transducer, a transom mount transducer may be used with epoxy inside a boat (“shoot-thru-hull” installation). For a transducer to be mounted inside the hull (shoot-thru, not thru-hull), the boat must be fiberglass, no core (contact your boat manufacturer if you are unsure). Test by placing a small amount of water inside the hull, placing the transducer on top of the water, then verifying the accuracy of the locators versus the current water depth.
Appendix A Testing the Installation Testing the Installation While it is possible to perform some checks with the boat trailered, the boat should be in the water to properly test the sonar portion of the installation. Press the POWER button and the GPSMAP 178C should power on. If the unit fails to power on, verify that the wiring adapter is seated properly in the back of the unit, the Red and Black wires are connected to the correct polarity, and that the fuse is installed and not blown.
Installing and Removing Data Cards The GPSMAP 178C uses optional Garmin marine BlueChart and MapSource data cards to display digital charts and maps on-screen. You may also transfer user data to data cards (pg 82) Data cards are installed in the card slot located at the bottom right of the unit. Data cards may be installed or removed at any time, whether the unit is on or off. Appendix A Installing and Removing Data Cards To install a data card: 1.
Appendix B Loran TD Loran TD System LORAN-C is a radio navigation aid operated and maintained in the United States by the United States Coast Guard. The name LORAN is an acronym for “LOng RAnge Navigation”. The LORAN system covers the entire United States and the U.S. Coastal Confluence Zone. From the perspective of a mariner, the system is used for ocean and coastal navigation.
The ‘LORAN TD Setup’ window contains the fields to select the Loran GRI-Chain Number, Primary and Secondary Stations, and TD Offsets. To setup Loran TD from the Main Menu: Appendix B Loran TD Setup 1. Using the ARROW KEYPAD, highlight the ‘Setup tab, then press RIGHT to highlight the ‘Units’ submenu tab. Highlight the “Position Format” field and press ENTER. You may also press MENU from the “Units” tab to display the ‘Loran TD On’ option. (If you use ‘Loran TD On’, skip to step 3.) 2.

Course— The desired course between the active ‘from’ and ‘to’ waypoints. Distance (Dist)— The ‘great circle’ distance from present position to a destination waypoint. Distance to Destination— The ‘great circle’ distance from present position to a Go To destination, or the final waypoint in a route.
Appendix E Navigation Terms DIS NORTH NORTH TAN CE TO DES TINA TIO N DESTINATIO WAYPOINT BRG TRK F SP EE D SE UR CO DES IR TRA ED CK OF Odometer— A running tally of distance travelled, based upon the distance between second-by-second position readings. Off Course— The distance you are off a desired course in either direction, left or right. Also referred to as ‘cross-track error’ or ‘course error’. Speed— The current velocity at which you are travelling, relative to a ground position.
Appendix F The chart below gives an approximate UTC (Universal Time Coordinate) time offset for the various longitudinal zones. Check with local charts for more detailed information. If you are in daylight savings time, add one hour to the offset. Longitudinal Zone Offset Longitudinal Zone Offset Time Offsets + A simple way to determine your local time offset is how many hours you are behind or ahead of UTC (also called ‘Greenwich’ or ‘zulu’ time).
Understanding Sonar If you are unfamiliar with basic sonar, or need help determining what is displayed on the graph, this section may be for you. This section is intended to help the novice user gain some understanding of how the GPSMAP 178C operates and how it can help improve their fishing productivity. To understand what the unit is displaying, it is important to have a general knowledge of how the unit works and how it determines what to display.
Appendix G Transducer Coverage Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. Cone angles may vary between different types of transducers. For example, a 50kHz frequency may provide a “wide” 40° cone angle, with a coverage width that is approximately 2/3 of the water depth. As shown in the sidebar, the 40° cone angle (50kHz frequency) approximately covers the area of a 20 foot diameter circle at a 30 foot depth.
Understanding the Graph It is important to understand that the unit does not display a 3-D representation of the underwater environment. The unit can display multiple things at the same time, but cannot determine where the return originated – only when it was received. Examples 1 and 2 provide a look at the underwater world from a top view, and illustrate how these views would be displayed on the graph. On both graphs it appears the fish and tree are side by side as shown in Example 1.
Appendix G Understanding the Graph ) Whiteline can also help you to determine the type of bottom structure that is displayed on the chart. By determining the hardness of the structure, you can make a better informed decision on the type of structure. Structure is hard— probably a rock or stump 114 GPSMAP178CManual.indd 114 Structure is soft— probably a mud pile Whiteline The GPSMAP 178C can help you to determine if the bottom is hard or soft.
Thermoclines One of the unique features offered by Garmin is See-Thru technology. See-Thru technology allows the GPSMAP 178C to “see” through thermoclines and helps locate fish where they live; and fish love thermoclines! A rough definition of a thermocline is a break in water where the water temperature changes faster than the water above it. Thermoclines are shown as the weakest colors (see pg. 14) Appendix G Understanding the Graph Thermocline 115 GPSMAP178CManual.
