Cleaning the ScreenNOTICECleaners containing ammonia will harm the anti-reflectivecoating.The device is coated with a special anti-reflective coating whichis very sensitive to skin oils, waxes, and abrasive cleaners.1 Apply an eyeglass lens cleaner specified as safe for anti-reflective coatings to the cloth.2 Gently wipe the screen with a soft, clean, lint-free cloth.ScreenshotsYou can capture a screenshot of any screen shown on yourchartplotter as a bitmap (.bmp) file. You can transfer thescreenshot to your computer.Capturing Screenshots1 Insert a memory card into the card slot.2 Select Settings > System > Display > Screenshot Capture> On.3 Go to a screen you want to capture.4 Hold HOME for at least six seconds.Copying Screenshots to a Computer1 Remove the memory card from the chartplotter, and insert itinto a card reader that is attached to a computer.2 From Windows®Explorer, open the Garmin\scrn folder on thememory card.3 Copy a .bmp file from the card and paste it to any location onthe computer.TroubleshootingMy device will not acquire GPS signalsIf the device is not acquiring satellite signals, there could be afew causes. If the device has moved a large distance since thelast time it has acquired satellites or has been turned off forlonger than a few weeks or months, the device may not be ableto acquire the satellites correctly.• Ensure the device is using the latest software. If not, updatethe device software (Updating the Device Software, page 1).• If the device is using an internal GPS antenna, make sure thedevice has a clear view of the sky so the internal antenna canreceive the GPS signal. If it is mounted inside of a cabin, itshould be close to a window so it can receive the GPS signal.If the device is mounted inside a cabin and cannot be placedin a location where the device can acquire satellites, use anexternal GPS antenna.My device will not turn on or keeps turning offDevices erratically turning off or not turning on could indicate anissue with the power supplied to the device. Check these itemsto attempt to troubleshoot the cause of the power issue.• Make sure the power source is generating power.You can check this several ways. For example, you cancheck whether other devices powered by the source arefunctioning.• Check the fuse in the power cable.The fuse should be located in a holder that is part of the redwire of the power cable. Check that the proper size fuse isinstalled. Refer to the label on the cable or the installationinstructions for the exact fuse size needed. Check the fuse tomake sure there is still a connection inside of the fuse. Youcan test the fuse using a multimeter. If the fuse is good, themultimeter reads 0 ohm.• Check to make sure the device is receiving is at least 10 V,but 12 V is recommended.To check the voltage, measure the female power and groundsockets of the power cable for DC voltage. If the voltage isless than 10 V, the device will not turn on.• If the device is receiving enough power but does not turn on,contact Garmin product support at www.garmin.com/support.My device is not creating waypoints in the correctlocationYou can manually enter a waypoint location to transfer andshare data from one device to the next. If you have manuallyentered a waypoint using coordinates, and the location of thepoint does not appear where the point should be, the mapdatum and position format of the device may not match the mapdatum and position format originally used to mark the waypoint.Position format is the way in which the GPS receiver's positionappears on the screen. Commonly displayed as latitude/longitude in degrees and minutes, with options for degrees,minutes and second, degrees only, or one of several gridformats.Map datum is a math model which depicts a part of the surfaceof the earth. Latitude and longitude lines on a paper map arereferenced to a specific map datum.1 Find out which map datum and position format was usedwhen the original waypoint was created.If the original waypoint was taken from a map, there shouldbe a legend on the map that lists the map datum and positionformat used to create that map. Most often this is found nearthe map key.2 On the chartplotter, select Settings > Units.3 Select the correct map datum and position format settings.4 Create the waypoint again.NMEA 0183 InformationType Sentence DescriptionTransmit GPAPB APB: Heading or track controller(autopilot) sentence "B"GPBOD BOD: Bearing (origin todestination)GPBWC BWC: Bearing and distance towaypointGPGGA GGA: Global positioning systemfix dataGPGLL GLL: Geographic position(latitude and longitude)GPGSA GSA: GNSS DOP and activesatellitesGPGSV GSV: GNSS satellites in viewGPRMB RMB: Recommended minimumnavigation informationGPRMC RMC: Recommended minimumspecific GNSS dataGPRTE RTE: RoutesGPVTG VTG: Course over ground andground speedGPWPL WPL: Waypoint locationGPXTE XTE: Cross track errorPGRME E: Estimated errorPGRMM M: Map datumPGRMZ Z: AltitudeSDDBT DBT: Depth below transducerSDDPT DPT: DepthSDMTW MTW: Water temperatureAppendix 25
