The screen with adhered glass with anti-reflective coating provides excellent readability for both day and night, as well as high-contrast digits that can be enlarged up to 36 mm.\u003c\/p\u003e \u003cp\u003eThe GNX 20 device is the first nautical instrument with a screen with attached glass that presents a combination of LCD segments by direct drive and a matrix field of points that allows graphic information to be displayed. By consuming little energy (25 mA) with a use of 350 mW (without backlight)\/400 mW (average level of backlight), this device is ideal for sailing boats, as well as a very useful instrument during navigation and fishing activities. Fully customizable user profiles show data related to wind, depth and speed. In addition, the GNX 20 device includes an automatic screen change function that allows you to switch between data screens without user intervention. It can be installed with the low-profile built-in mounting bracket or with the optional flush mounting bracket in order to enjoy the best glass rudder solution and customize your boat as you wish.\u003c\/p\u003e \u003ch3\u003eSpecifications:\u003c\/h3\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch4\u003ePhysical and performance\u003c\/h4\u003e \u003c\/div\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eScreen size (Width\/High)\u003c\/td\u003e \u003ctd\u003e83 x 60 mm; 101.6 mm diagonal (3.3” x 2.4”; 4.0” diagonal)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDimensions of the unit (Width\/High\/Depth)\u003c\/td\u003e \u003ctd\u003e110 X 115 X 30 mm (4.33\" X 4.53\" X 1.18\")\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eVoltage scale\u003c\/td\u003e \u003ctd\u003e9-16 V (from NMEA 2000)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eClassification of water resistance\u003c\/td\u003e \u003ctd\u003eIPX7\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWeight\u003c\/td\u003e \u003ctd\u003e230 g (8 oz)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eAssembly options\u003c\/td\u003e \u003ctd\u003eFlat or Flush\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eType of screen\u003c\/td\u003e \u003ctd\u003eStandard LCD, monochrome\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch4\u003eCharacteristics\u003c\/h4\u003e \u003c\/div\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eCompatible with NMEA 0183\u003c\/td\u003e \u003ctd\u003eYes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eAutomatic ignition\u003c\/td\u003e \u003ctd\u003eYes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eTemperature range\u003c\/td\u003e \u003ctd\u003eFrom 5° to 158°F (from -15° to 70°C)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMisc\u003c\/td\u003e \u003ctd\u003e \u003cul\u003e \u003cli\u003eDimensions of the unit (height X width X depth): 11 cm X 11.5 cm X 3 cm\u003c\/li\u003e \u003cli\u003eScreen size (diagonal): 10.16 cm (4\")\u003c\/li\u003e \u003cli\u003eWeight: 230 g (8 oz)\u003c\/li\u003e \u003cli\u003eTemperature range: from -15 °C to 70 °C (from 5 °F to 158 °F)\u003c\/li\u003e \u003cli\u003eScreen type\/color: standard LCD, monochrome\u003c\/li\u003e \u003cli\u003eMaximum digit display size: 36.4 mm\u003c\/li\u003e \u003cli\u003eScreen with attached glass: yes\u003c\/li\u003e \u003cli\u003eSeveral color palettes: yes\u003c\/li\u003e \u003cli\u003eCustomizable user profiles for navigation with sailing and motor boats: yes\u003c\/li\u003e \u003cli\u003ePower consumption: 0.35 W (daytime use); 0.4 W (night use)\u003c\/li\u003e \u003cli\u003eCompatible with NMEA 2000® and NMEA 0183: yes\u003c\/li\u003e \u003cli\u003eSingle, double and triple display functions: yes\u003c\/li\u003e \u003cli\u003eGraphics: yes\u003c\/li\u003e \u003cli\u003eBrackets for flush\/recess mounting: yes\u003c\/li\u003e \u003c\/ul\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eVitrified screen\u003c\/td\u003e \u003ctd\u003eyes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eUser profiles\u003c\/td\u003e \u003ctd\u003eYes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eNMEA 2000® certified\u003c\/td\u003e \u003ctd\u003eyes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSafety distance of the compass\u003c\/td\u003e \u003ctd\u003e209 mm (8.25 in.)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eEnergy consumption\u003c\/td\u003e \u003ctd\u003e0.35 W (day); 0.4 W (night)\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e\u003c!-- sr-faq v=1 vendor=garmin source_sha256=f912b93d5d2155d430e08fd6b6338a826e488177732735ce81b7a7570cb0a808 --\u003e\u003ch3\u003eFAQs\u003c\/h3\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the correct pilot hole size for mounting the GNX 20?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eDrill 2.8 mm (7\/64 in.) pilot holes for securing the GNX 20 during installation.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow should unused connectors be protected during installation?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eCover unused connectors with the attached weather caps to prevent corrosion.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes the GNX 20 require gasket and sealant for mounting?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eYes.
