Product Description

The Garmin GTN-750 is more than a "super-sized" GTN-650, although that is the most obvious difference. This larger size not only allows the GTN-750 to show more information, it allows that information to be more usable and digestible.

  • GTN-650: The GTN-650 is 2.65" tall, and the display measures 4.9" diagonally. The display shows 600 x 266 pixels.
  • GTN-750: The GTN-750 is significantly taller, at 6". This accommodates a display which measures 6.9" diagonally. The display shows 600 x 708 pixels.

The GTN-750 display measures "only" 41% larger in corner-to-corner size. However, the true measurement is the information it conveys to the pilot. The GTN-750 shows 166% more information, more than twice as much as the GTN-650. In fact, the GTN-750 is closer to triple the GTN-650's content than double.

This larger display size allowed Garmin to format the GTN-750's display for greater effectiveness. For example, the GTN-750 feature include:

  • The COMM and NAV frequencies are at the top of the display (rather than the side), which opens up a dramatically wider and more informative Moving Map / MFD.
  • The larger touchscreen display allows direct data entry, rather than scrolling on the GTN-650.
  • The display can show FliteCharts, which are reproduced AeroNav Services terminal procedures charts. (Please note that the aircraft position is not shown.)
  • The display can also show Garmin ChartView, which are reproduced Jeppesen terminal procedures charts. The aircraft position is shown with ChartView for better awareness.
  • The GTN-750 is capable of acting as a Weather Radar Indicator for the Garmin GWX-68 / GWX-70 / GWX-75 Transmitter / Receiver.

This larger display undeniably occupies more height in the radio stack. However, the GTN-750 has an additional ability to free up panel space. In addition to the ability to control a remotely-mounted Transponder (much like the GTN-650), the GTN-750 can be used to control remotely-mounted Garmin Audio Panels, such as the GMA-35 and GMA-35c (with Bluetooth). This gives you fingertip control of Communications and the Intercom. Using a remotely-mounted Audio Panel also frees up valuable vertical space in your radio stack. This feature may be the difference which allows you to fit the GTN-750 in your panel. It also puts precious panel space to its best and most-useful purpose.

The GTN-750, which is the next-generation version of the GNS-530W, will serve as the hub of your avionics. The Navigation and Communication functions are more powerful, but also easier to use. The Multi-Function Display (MFD) capabilities are enhanced considerably, especially when paired with an ADS-B In Receiver.

Most of the GTN-750's features, including a high-resolution moving map, graphical flight planning, terrain avoidance, traffic alerts, weather information, and taxiway diagrams, are made possible by the larger 6.9" color display with a touch interface.

The GTN-750 has a significantly larger and higher-resolution display than the GNS-530W. It has a "pinch and zoom" touch interface, similar to a smartphone. (Some pilots love the touch interface, and others miss the traditional buttons and knobs.) Raised bezels offer a physical connection to "anchor" the pilot's hand during operation.

The GTN-750 includes a tremendous amount of capability, and these are only the highlights. (Please send us an email if you would like the Pilot's Guide, and we will be happy to send you a copy for your review.)


The GTN-750 will allow WAAS-GPS-enabled precision IFR LPV approaches, in addition to standard VOR / Localizer / Glideslope navigation.

There are thousands of FAA-approved LPV WAAS approaches, with more being added regularly. The FAA's stated goal is to have a WAAS approach available for every public runway at least 3,200 feet long. To see if the airports you use offer WAAS capability, please click here for the FAA's information about GPS/WAAS Approaches.

One of the admired features of the CNX-80/GNS-480 is the ability to navigate with Victor airways. The GNS-430W and GNS-530W lack this feature, but it is present in the GTN-750.

Even when flying VFR, the GTN-750 can create a virtual precision approach, with vertical guidance. The keys to safety are consistency and precision, and this feature allows you to treat a VFR approach like an IFR approach.



The COMM frequencies may be tuned in either 25 kHz or 8.33 kHz increments. The 8.33 kHz channel spacing is critical to meeting European requirements.

The GTN-750 will decode the Morse code identifier automatically.  It will also display the identifier from the database, confirming you are communicating with the correct party.

It is quick and easy to call for help.  When the pilot holds down the volume knob or remote active/standby flip-flop switch for two seconds, the GTN-750 will automatically set the emergency frequency (121.5 MHz) as your active frequency. When you are busy and time is important, just hold down the knob and key the mic to get help.


Multi-Function Display (MFD)

The GTN-750 has a high-resolution Moving Map, capable of showing Topographical features, Victor Airways, Terrain (color-coded relative to your current altitude), Weather Radar, WX-500 Stormscope Lightning (if equipped), and Traffic. Please note that Terrain and Weather Radar information cannot be shown at the same time. Both types of information are color-coded according to the relative threat, and it would be confusing to see "red" same-altitude terrain and "red" high-intensity precipitation at the same time.

Traffic information is available on a dedicated page. But if you are viewing other information on the MFD, a pop-up window will still bring traffic information to your attention.

It is possible to "pan" the map to a different region simply by dragging your finger across the display, much as you would a smartphone or tablet.

Garmin's SafeTaxi database is available to show runways, taxiways, FBOs, and hangars on the display. This boosts safety by allowing the pilot to ensure they are following the Ground instructions. (It also makes it more difficult to get lost at an unfamiliar airport!) The MFD will also show "Hot Spots", which are confusing or complicated areas where extra care is needed for safety.

If you also have ADS-B In, the GTN-750 can display up to 60 traffic targets with both audio and visual alerts. Subscription-free ADS-B In weather information includes NEXRAD radar, graphical AIRMET, Winds & Temperature Aloft, Lightning, Turbulence, Icing, Cloud Tops, and much more.



The GTN-750 feels similar to the GNS-530W in operation, but a "flattened" menu structure makes it faster and easier to reach the function you need.

If you have a second GTN-series radio, or a GNS-430W / GNS-530W, they are able to communicate and share the active flight plan.

The GTN-750 will show you the entire planned flight on the moving map. When the inevitable changes are introduced, the "rubber band" feature allows you to drag any segment of your route to match the new clearance.

As a WAAS GPS, the GTN-750 is able to serve as the position source for your ADS-B Out solution.

The GTN-750 has the ability to control a remotely-mounted Transponder, saving space in your radio stack.


The GTN-750 is very flexible, and may be used with these Glideslope Indicators, HSIs, and Glass Panels (the Garmin units are the official choices):
