Affordable, reliable replacement for mechanical DG and HSI

The compact and cost-effective G5 is a breakthrough. This 3.5” LCD screen fits in a standard 3 1/8” instrument hole and is more than a backup – it’s a standalone primary instrument for heading and course information. Far more reliable than vacuum-powered instruments, the built-in battery means G5 will continue to operate even if your electrical system should fail. Connect to your GTN or GNS series navigator and the G5 can also display VOR/LOC/GPS information. It will even drive popular autopilots made by Bendix/King, S-Tec, and Century. Approved for use in IFR and VFR flight.


  • GMU 11 magnetometer for heading
  • GAD 29B ARINC 429 adapter to connect to your onboard GPS and autopilot (see list below)
  • Internal 4-hour battery


Dual G5 Installation Options Offer Added Redundancy

The G5 electronic flight instrument offers a wide range of flexible panel configuration options along with the reliability associated with a modern electronic flight instrument. Up to two G5 displays can be incorporated into a single aircraft panel in several approved combinations, including the attitude, DG/HSI or turn coordinator positions. In dual installations, a secondary G5 can revert to display attitude information in the unlikely event of a failure in the primary attitude indicator position. A pilot-selectable menu on the G5 DG/HSI enables the manual selection and interchange between the attitude indicator and DG/HSI display.

Autopilot Integration

Utilizing the new GAD 29B adapter, the G5 directional gyro (DG)/horizontal situation indicator (HSI) can interface with a variety of autopilots to provide heading and course error to drive the autopilot. With a compatible navigation source, the G5 can also interface with select autopilots for coupled flight in heading and navigation modes. Additionally, when interfaced with a GTN 650/750 or GNS 430W/530W, the G5 can provide GPSS roll steering navigation from the navigator to the autopilot. Pilots can simply select GPSS on the G5 and heading mode on the autopilot and the autopilot will fly smooth intercepts, holding patterns, procedure turns and more.

Third-party autopilot support is expected to include the following autopilots:

  • Century II/III
  • Century IV (AC), IV (DC)
  • Century 21/31/41
  • Century 2000
  • Cessna 400B
  • Cessna 300 IFCS/400 IFCS

Buying the G5 and removing vacuum pump. Having trouble finding cover plate and gasket that covers the vac pump hole. Anyone done this in a Lyc O-320-D2J? Thanks
David K on Aug 23, 2019
BEST ANSWER: Check with a local engine repair shop. I did. Very Reasonable from Don George Aircraft Parts in Orlando, Fl
Does this have a heading bug that will "talk" to an S-TEC 40 autopilot?
Chris H on May 1, 2017
BEST ANSWER: The Garmin G5 will not "talk" to a S-TEC 40 autopilot.
I assume the DG/HSI requires it be connected to a navcom radio. Are only Garmin nav/comms compatable and if so what nav/comms are compatable? Does it work with only GNC or GTR models or will it also work with an SL 30 or SL 40?
A shopper on Apr 23, 2017
BEST ANSWER: These units are not required to be connected to a NavCom. Please see for compatibility.
I have a 1964 PA 28 Piper Cherokee IFR all steam gauges, and am considering a G5 HSI and Garmin GFC 500 autopilot. are these suitable for the aircraft? and do I need any other components?
Thanks; Rich Read
moongazer on Jun 26, 2020
BEST ANSWER: I would recommend contacting our avionics shop at 513.735.9595 to discuss what is required for this to work in your particular aircraft.
I have a GNS 430 WAAS and an STEC 50 AP, will the G5 be compatible with this set up? Looks like it has become compatible recently.
A shopper on Apr 17, 2020
BEST ANSWER: Yes, it is.
I noticed in the fine print it state the altitude indicator is sold separately. yet on the DG it shows altitude...please there another piece needed to give you altitude?
A shopper on Jan 21, 2020
BEST ANSWER: The Upper G5 is the Attitude indicator. The bottom is the DG/HSI. Each unit is sold separately.
I have a Piper P28/151 with a Garmin 430 WAAS. I am thinking about upgrading my avionics by putting either a Garmin G-5 DG/HSI or the ASPEN unit. A friend of mine with a C-182 has the Aspen and I fly it on occasion and find it OK, but I have heard that the Aspen has a "glitch" if the pitot tube freezes. So, what are your thoughts on putting in the Garmin G-5 (maybe both the DG/HSI and the Attitude Indicator) vs. the Aspen Pro 1000?

Thanks for the input -

Bob Ross
Bob R on Dec 26, 2019
BEST ANSWER: We have several G5 in our training fleet. The preform well. I also fly with an aspen unit and have not heard of the glitch you are referring to.

If the K10-00280-00 is capable of being used as and attitude indicator and an HSI what is the difference between the K10-00280-00 and the K10-00280-20?
Sammy 9 Toes on Sep 19, 2019
BEST ANSWER: The Attitude indicator is not capable of displaying the DG/HSI. The DG/HSI can revert to the attitude indicator if the attitude indicator has a fault.

A shopper on May 25, 2019
BEST ANSWER: I would recommend contacting Garmin as the STC list changes.
Is the G5/HSI approved for the Cessna C340 and the B400 Auto pilot?
Jim T on May 15, 2019
BEST ANSWER: Yes, the 340 is on the AML and the B400 autopilot is compatible. Discuss with your installer if you are adding an attitude indicator as the autopilot uses the attitude indicator to drive the autopilot.
Will the G5 be compatible with my 1977 PA32 Altimatic III autopilot?

I have the Garmin G5 (experimental) and am looking for the GMU 11 magnetometer to install with it. Garmin part number is 010-01788-00. every time I search it on your website it comes up with an HSI which I don't need or want. Garmin list this part number as an accessory to the G5 and MSRP is 275.00. Can you get this part or do I need to look elsewhere ?
