Big capabilities come in a small package with the GNX 375 navigator. With its bright, clear high-resolution touchscreen display, you can have the advanced navigation functions you’ve always dreamed of — while meeting the requirements for ADS-B “Out” and experiencing the benefits of ADS-B “In.” Entering flight information is a cinch, and accessing every function is fast and easy. It’s equally at home in certificated aircraft or an experimental aircraft. And it’s the same 2” height as older navigation equipment and can allow you to keep the composite legacy CDIs already in your aircraft to minimize installation cost¹. That makes GNX 375 the smart, affordable way to add next-generation navigation to your favorite airplane.
Perfect Touch
The moment you power up GNX 375, you’ll see a familiar Garmin homepage on the 4.8” display, which puts the most important functions within only a few touches. Navigate to dedicated pages for the moving map, traffic, terrain, weather, nearest airports, flight plan, procedures, waypoint information, utilities and more. With shortcuts available to the flight plan and Direct-to functions on almost every page, navigation features are usually just a tap away. Use your finger to pan and zoom on any map, traffic and terrain page. Enter waypoint data with the on-screen keyboard. And touch the home button to get you back to the main page at any time.
For added control stability in flight, a shelf across the lower edge of the display serves to steady your hand in smooth and turbulent flight conditions. And if you prefer traditional controls, the concentric knobs provide yet another way to control many of the GNX 375 navigator’s functions.
Intuitive Navigation
With GNX 375, building and modifying flight plans is simple. As you enter waypoints, our FastFind feature automatically begins searching for the nearest identifier as soon as you start typing, so — in most situations — a press or 2 reveals just what you were thinking. You can also create holds, insert Victor airways and corresponding exit options, and add departures, arrivals and instrument approach procedures. Additionally, you can edit your route using the map screen; a handy "rubber band" feature lets you grab any leg of your flight plan route and move it to accommodate a deviation or ATC amendment to your flight plan.
A variety of dynamically drawn and displayed maps provide situational awareness and context to the flight plan by highlighting visual reporting points, navaids, SafeTaxi® diagrams and hazards such as obstacles, power lines and terrain. Plus, the Smart Airspace™ feature automatically highlights airspace close to your current altitude and de-emphasizes airspace away from the current altitude.
Advanced Approach to IFR
The SBAS/WAAS-certified GPS receiver can allow you to fly GPS-guided LPV glidepath instrument approaches down to as low as 200’, greatly expanding your operational capability. You can also access newer localizer performance (LP) and all area navigation (RNAV) approaches. Precise course deviation and roll steering outputs can be coupled to our GFC™ 500 and GFC 600 autopilots as well as select third-party autopilots so that IFR flight procedures such as holds, NextGen radius-to-fix (RF) legs and missed approaches may be flown automatically. In addition, the GNX 375 navigator lets you create and execute custom holding patterns over an existing waypoint or user-defined waypoint.
Plus, when operating in VFR conditions, GNX 375 can provide advisory vertical approach guidance based on a published glidepath angle or a 3-degree approach glideslope from the runway threshold, while considering terrain and obstacle clearance. With this advisory guidance, you’re able to fly more consistent, precise vertical glidepaths into a variety of airfields.
Add ADS-B “Out” and “In”
With its built-in 1090 ES transponder, GNX 375 allows you to meet ADS-B “Out” requirements with a single installation, while its dual-link ADS-B “In” receiver provides a complete picture of ADS-B traffic targets as well as subscription-free weather in the U.S. For example, the ADS-B weather link allows you to access animated NEXRAD imagery, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more.
Additionally, our patented TargetTrend™ relative motion technology offers a faster, more intuitive way to judge the direction and closure rate of intruding targets in relation to your aircraft’s position. For example, if traffic is ahead of you and traveling along the same track but at a slower rate, the motion vector would point opposite of its indicated direction of flight to show you are overtaking the traffic. Spoken audio alerts call out potential flight path conflicts (“Traffic, 10 o’clock, same altitude, 2 miles”) to get you looking in the right direction. And, at the start or end of each flight, TerminalTraffic™™ technology provides the most comprehensive picture of ADS-B equipped aircraft and ground vehicles in the airport environment. ADS-B equipped aircraft in-flight are easily distinguished from ground vehicles and taxiing aircraft, which are displayed using distinct colors and symbols. All information is presented on a simple, easy-to-understand SafeTaxi diagram with reference to runways, taxiways, hangar locations and more.
Cockpit Integration
The GNX 375 navigator interfaces with Garmin flight displays, including G3X Touch (experimental and certified), G5 (experimental and certified), G500/G600, G500 TXi/G600 TXi as well as select third-party displays¹ to provide navigation outputs. It’s also compatible with many older, composite-input based CDIs — allowing you to keep your existing CDI and have an easier, more cost-effective installation¹. Better still, GNX 375 can be interfaced with a variety of compatible cockpit displays to provide ADS-B weather and traffic information.
And for even more work-saving convenience, you can use the built-in Connext technology to stream information between GNX 375 and compatible Garmin portables and mobile devices running the Garmin Pilotor FltPlan Go apps. You can create flight plans at home and upload them at the airport. And you can stream GPS data, backup attitude information (from the built-in AHRS) as well as traffic and weather to your mobile device or Garmin portable, making them even more useful cockpit companions.
Plus, our optional Flight Stream 510 installs in the memory card slot of GNX 375 to enable our Database Concierge database transfer and management capabilities via our Connext gateway. At home, you can download selected databases onto your mobile device by using the Garmin Pilot app. Then, once you get to the airport, Flight Stream 510 will automatically establish a wireless connection to the Garmin Pilot app and upload the databases from your device to your GNX 375 in minutes.

G5 Electronic Flight Instrument for Certificated Aircraft
Glass Upgrade for DG/HSI and Attitude Instruments in GA Aircraft
- Replaces traditional electromechanical instruments; can be configured in attitude, DG/HI/HSI and turn coordinator positions
- Bright, sunlight-readable 3.5" LCD color display, sized to fit standard 3-1/8" instrument cutout
- Certified via approved model list (AML) for STC'd installation on more than 560 aircraft makes and models
- Includes a 4-hour backup battery with battery status indicator
- Dual G5 installation offers reversionary display capability plus the added redundancy of dual ADAHRS and dual backup batteries

The G5 electronic flight instrument delivers exceptional performance, reliability and ease of installation as a drop-in replacement for primary attitude and/or directional gyros in type-certificated fixed-wing aircraft. For select aircraft equipped with G500 or G500 TXi, G5 can also be used as a standby flight instrument to those systems. Providing an economical upgrade path via a comprehensive approved model list (AML), the compact and cost-effective G5 is bringing modern “glass cockpit” reference to thousands of aircraft that would otherwise depend on older, vacuum-driven equipment.
Affordable Glass Solution
Designed for installation in FAR Part 23 Class 1 and Class 2 aircraft (singles and twins weighing less than 6,000 lbs), the 3.5" G5 display fits into a standard 3-1/8" round cutout, taking up just a fraction of the space and weight previously required by conventional gyro-based instruments. It's valid for flight under VFR and IFR conditions. And, by combining visual cues and data readouts once scattered across a myriad of instruments, G5 makes flight information easier to scan -- so pilots can respond more quickly and intuitively to any inflight situation.
Rock-solid Attitude Reference
When configured as a primary attitude indicator, G5 uses solid-state AHRS reference to provide smooth, steady and reliable horizon-based pitch and roll indications. In addition to aircraft attitude, G5 will also support display of airspeed, altitude, vertical speed, slip/skid, turn rate, configurable V-speed references, barometric setting and selected altitude -- as well as visual alerts upon arriving at a preselected altitude. A built-in GPS receiver provides highly accurate groundspeed and ground track readouts. Plus, a dedicated rotary knob on the unit allows for easy adjustments to altitude bugs and barometric pressure settings.
Gain A Clearer Sense of Direction
To provide even more situational awareness, G5 is also approved for installation as a replacement heading indicator/directional gyro (HI or DG) or horizontal situation indicator (HSI) in your panel. When paired with an affordable GMU 11 magnetometer, GAD™ 29 navigation data interface and select VHF Nav/Comms or GPS navigators, G5 can serve as your primary reference source for magnetic heading, VOR/LOC guidance and/or GPS course guidance — as well as providing distance and groundspeed indications. The unit displays both vertical and lateral GPS/VOR/LOC course deviation when available. And you can use the G5 instrument’s rotary knob to easily make and adjust course selections — or to control heading bug settings in DG installations. For added system integration, a single magnetometer can supply heading information to 2 G5 units simultaneously. Additionally, G5 can provide heading output to select third-party autopilots (with GAD 29B).
Experience an Innovative Autopilot System
Reduce workload and fly with more confidence by pairing G5 with our GFC™ 500 digital autopilot. GFC 500 offers silky-smooth flight control and advanced, safety-enhancing capabilities at a cost-effective price never before available on certified aftermarket solutions for light, fixed-wing aircraft.
Based on our revolutionary GFC 700 installed in thousands of new aircraft, GFC 500 offers Enhanced Stability and Protection, overspeed and underspeed protection and a dedicated LVL button. Plus, it provides the ability to fly coupled GPS and IFR approaches with compatible Garmin navigators and Nav/Comms as well as an optional go-around switch and automatic and manual electric trim.
As part of the GFC 500 system, G5 provides input and display of attitude preselect, heading bug, vertical speed bug, airspeed target and flight director command bars, while a dedicated GMC 507 autopilot controller provides large dedicated keys, knobs and control wheel for mode, altitude, heading and vertical speed selection.
Dual Displays Double Your Options
By installing dual G5 displays in your panel, you not only gain dedicated instruments for attitude reference and directional gyro/HSI guidance, but you also gain the advantages of backup redundancy with dual ADAHRS and reversionary display capability. In such installations, a secondary G5 can revert to display attitude information (consolidated with heading indication) in the unlikely event of a failure in the primary attitude indicator position. For added "get home" protection, each G5 display is available with a backup lithium-ion battery, which can provide up to 4 hours of emergency operation in case of an aircraft electrical outage or shutdown.

For pilots who want the best of the basics in audio control, combined with rich "home theater" quality sound, the GMA 342 all-digital audio panel is a perfect fit. It's affordably priced yet loaded with features previously found only on high-end audio management systems. Plus, for easy system upgrade, it offers direct slide-in replacement for legacy GMA 340 or select third-party audio control panels. So it doesn't take long for your installer to pull out the old and slide in the new.
Easy Connections, Better Communications
With its advanced sound processing and distribution features, GMA 342 offers a superior inflight audio experience. It can support dual comm, dual nav, 3 aux receivers and 2 wired stereo music inputs --enhanced with bass boost levels, equalizer settings and exclusive 3D Audio technology that spatially separates the multiple communication sources entering your headset. Other highlights include industry-leading Auto Squelch, a digital clearance recorder and marker beacon receiver. A 3.5-mm audio jack on the faceplate allows smartphones, tablets or music players to be plugged in and routed through the cabin headsets, with selectable instant muting when radio calls are received from ATC.
Enjoy a Little Traveling Music
GMA 342 really shines when it comes to music support. You can connect up to 2 dedicated stereo music sources via the unit's rear connectors (think of a wired SiriusXM satellite music receiver plus an auxiliary music device), and then add a third mobile device into the front plug-in jack. You can select any one of these 3 sources from the audio unit, so it's easy to route cell phone calls or music inputs to pilot, copilot and passenger headsets -- up to 6 locations in all.
Listen in Virtual 3-D
For your radio communications, advanced 3-D digital sound processing, first introduced to general aviation by Garmin, enables GMA 342 to approximate how the human ear normally hears and registers multiple audio sources in space. With stereo headsets, incoming audio is spatially separated to reflect how different audio sources come from different directions around you. This makes it easier to distinguish one source from another -- and helps you focus on the higher-priority calls coming into your headset. For example, COMM 1 will seem like it's coming from the left while COMM 2 will seem to be coming from the right.
Get Instant Replay on ATC Calls and Clearances
An automatic digital voice recorder on GMA 342 continuously captures the last 60 seconds of incoming active comm audio for instant playback with a single button press. Any pilot who's ever missed an ATC call, frequency assignment or clearance amendment will appreciate the value of this handy "say again" function.
High-performance Auto Squelch
To further enhance the cockpit audio experience, advanced Auto Squelch technology on GMA 342 automatically adapts to a quiet or noisy environment without clipping words or cutting out during conversation. A high-performance digital signal processor constantly monitors ambient noise level and automatically adjusts the mic squelch level required to keep intercom conversation as comfortable and natural as possible -- whether you're talking over engine noise in flight or quietly going through your preflight checklist on the ground. The unit's Auto Squelch technology automatically adjusts for these variances, allowing you to speak at normal levels, no matter what the ambient sound conditions may be.
Easy Installation/Upgrade
Upgrading the audio experience in your cockpit is easy with GMA 342. It's fully rack-and-pin compatible in dual-Comm installations with the Garmin GMA 340 as well as select third-party audio panels. So, swap-out replacement takes minimal downtime. The audio panel's built-in intercom and marker beacon help further reduce installation time for the system. And since it can operate on either 14 or 28 volts, there's no need for any external voltage regulators or the wiring that goes with them. Fast, easy, affordable -- that's the GMA 342 audio upgrade path.
