It runs on 10 to 32 V and is rated IPX7, with a fully-gasketed polycarbonate case and an anti-glare glass lens for life in the cockpit.\u003c\/p\u003e\u003cp\u003eOn a NMEA 2000 network it can show sensor and system data such as depth, speed, wind, heading, and battery voltage, depending on what is installed on the boat. The screen layout is flexible, with options to show one reading large or split the page into two or three fields, plus graphs on supported pages. An optional NMEA 0183 data cable can be used to bring in data from a single NMEA 0183 talker.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eInverted 4 inch monochrome LCD with maximum digit height up to 36.4 mm for quick reads from a few feet away\u003c\/li\u003e\n\u003cli\u003eSupports single-field, dual-field, and triple-field layouts, plus graph pages for trending data\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 and NMEA 0183 compatible (NMEA 0183 input requires an optional data cable)\u003c\/li\u003e\n\u003cli\u003e10 to 32 V input, with low typical power use (about 0.35 W daytime and 0.4 W at night) and 1.35 W max\u003c\/li\u003e\n\u003cli\u003eIPX7 water resistance with a fully-gasketed polycarbonate housing and anti-glare glass lens\u003c\/li\u003e\n\u003cli\u003eDimensions without sun cover: 110 x 115 x 30 mm (4.33 x 4.53 x 1.18 in.)\u003c\/li\u003e\n\u003cli\u003eCompass-safe distance: 209 mm (8.25 in.) to help plan a clean dash layout\u003c\/li\u003e\n\u003cli\u003eCan share backlight and color settings across NMEA 2000 or NMEA 0183 networks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis display is best thought of as a repeater and organizer for the data already on your boat. What you see depends on the sensors and sources available on your NMEA 2000 backbone or through the connected NMEA 0183 device. If you have Nexus instruments and sensors, data can be brought into the system using a GND 10 bridge (sold separately).\u003c\/p\u003e\u003cp\u003eFor viewing comfort, plan the mounting angle so the screen stays within a reasonable line of sight. For the GNX 21 inverted LCD, mounting at less than a 50 degree viewing angle helps avoid color inversion when you are off to the side.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe unit supports flush or flat mounting on a dash panel. For flush installs, a 90 mm (3.5 in.) hole saw cutout is used, and the mounting surface should be flat so the bezel seats evenly and the case is not stressed when tightened.\u003c\/p\u003e\u003cp\u003eWhen mounting in a wet area, use a proper marine sealant around the gasket line to keep water from finding its way behind the dashboard. Unused connectors should remain capped to protect the contacts from corrosion.\u003c\/p\u003e\u003ch6\u003eElectrical and network integration\u003c\/h6\u003e\u003cp\u003ePower and NMEA 2000 data both come from the NMEA 2000 network connection, so the backbone needs to be wired and terminated correctly. If the network power wiring is unknown or mixed between brands, isolating the NMEA 2000 power feed can help prevent ground and power issues.\u003c\/p\u003e\u003cp\u003eFor battery management, it helps to have the NMEA 2000 network powered through an ignition circuit or an in-line switch instead of leaving the backbone energized at all times.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis is a good match for boats that want a dedicated instrument screen that stays readable in bright sun and at night without tying up a chartplotter window. It works well on sailboats where wind and speed pages are always in view, and on powerboats where depth, speed over ground, heading, and battery voltage are the everyday checks.\u003c\/p\u003e\u003cp\u003eWith low typical power draw, it also makes sense for boats that spend time on the hook and still want a clear cockpit readout while running off house batteries.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse salt spray with fresh water and wipe the lens with a soft cloth to keep the anti-glare surface clean. During seasonal checks, inspect the dash seal and mounting fasteners, especially if the panel sees vibration or frequent washdowns.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e010-N1142-10\u003c\/span\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":53721604554933,"sku":"QBP084965","price":367.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1280488_qbp084965.jpg?v=1794119262"},{"product_id":"qbp219828","title":"Boss Audio - MRH7 Universal Waterproof Radio Cover","description":"\u003cp\u003eThe MRH7 Universal Waterproof Radio Cover by Boss Audio provides a practical and protective solution for upgrading your boat's audio system.
