Changing the Fuse in the Power Cable1 Open the fuse housing .2 Twist and pull the fuse to remove it .3 Insert a new 3 A fast-blow fuse.4 Close the fuse housing.My sonar does not work• Push the transducer cable all the way into the back of thedevice.Even if the cable seems to be connected, you should pushfirmly so that it is fully seated.• Press , and ensure sonar is enabled.• Select the correct transducer type (Selecting the TransducerType, page 20).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. This is 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 Select Settings > Units.3 Select the correct map datum and position format settings.4 Create the waypoint again.My device does not display the correct timeTime is set by GPS position and time zone setting.1 Select Settings > Units > Time Zone.2 Ensure the device has a GPS fix.NMEA 2000 PGN InformationTransmit and ReceivePGN Description059392 ISO acknowledgment059904 ISO request060928 ISO address claim126208 NMEA: Command, request, and acknowledge group function126996 Product information127250 Vessel heading128259 Speed: Water referenced128267 Water depth129539 GNSS DOPs129799 Radio frequency, mode, and powerPGN Description130306 Wind data130312 TemperatureTransmitPGN Description126464 Transmit and receive PGN list group function127258 Magnetic Variance129025 Position: Rapid update129026 COG and SOG: Rapid update129029 GNSS position data129283 Cross track error129284 Navigation data129285 Navigation route and waypoint info129540 GNSS satellites in viewReceivePGN Description127245 Rudder127250 Vessel heading127488 Engine parameters: Rapid update127489 Engine parameters: Dynamic127493 Transmission parameters: Dynamic127498 Engine parameters: Static127505 Fluid level129038 AIS class A position report129039 AIS class B position report129040 AIS class B extended position report129794 AIS class A static and voyage related data129798 AIS SAR aircraft position report128000 Nautical leeway angle129802 AIS safety-related broadcast message129808 DSC call information130310 Environmental parameters130311 Environmental parameters (obsolete)130313 Humidity130314 Actual pressure130576 Small craft statusThis data applies only to NMEA 2000-compatible products.NMEA 0183 InformationTransmitSentence DescriptionGPAPB APB: Heading or track controller (autopilot) sentence "B"GPBOD BOD: Bearing (origin to destination)GPBWC BWC: Bearing and distance to waypointGPGGA GGA: Global positioning system fix dataGPGLL GLL: Geographic position (latitude and longitude)GPGSA GSA: GNSS DOP and active satellitesGPGSV GSV: GNSS satellites in viewGPRMB RMB: Recommended minimum navigation informationGPRMC RMC: Recommended minimum specific GNSS dataGPRTE RTE: RoutesGPVTG VTG: Course over ground and ground speedGPWPL WPL: Waypoint locationGPXTE XTE: Cross track errorPGRME E: Estimated errorPGRMM M: Map datum40 Appendix
