Garmin AXIS, Next Generation Integrated Flight Display

Will any of the hardware be at OSH for us to gawk at? I've been planning a panel refresh for some time to replace my 2-screen non-touch G3X and TruTrak GX Pilot autopilot, all of which are showing signs of age. My com/nav suite, consisting of an SL 30, GTN 650, and a PE audio panel, seems to be aging more gracefully. That said I'll probably yank everything and start over, but I want to learn more about the new system and weigh the pros and cons of maybe keeping select components, like the GTN, from my current setup. In any event Looks like I finally got the timing right on something. :sneaky:

Absolutely. We will have some great opportunities to get hands on experience with the AXIS equipment at Airventure 2026!

We would be happy to work through the specifics of your installation with you there. You can always contact us directly at [email protected] as well, where we can help talk through the options for your panel upgrade.

Thanks,

Justin
 
Yes, a GMU 22 connected directly to a GSU 25 or GSU 73 is supported in the AXIS system.
How About the GMA35C audio panel?

Currently I have the GMA35C integrated to my GTN750Xi.

Would the Axis system be able to command the Audio panel, through the HSDB connection to the GTN750Xi?

How about VPX-PRO? Is there an app / widget for VPX integration?
 
The way I read this, it seems like a compelling way to "IFR-ize" an existing VFR G3X system, without having to do a lot of rewiring or cutting your panel. Currently, a VFR bird with G3X Touch that wanted to update to allow for IFR would at a minimum have to add:
  • IFR GPS (GPS 175 or similar) - new panel hole
  • ARINC 429 (GAD 29)
  • A second NAV/COM radio (GNC 255A or similar) - new panel hole
  • Audio panel (GMA 245R or similar) - new panel hole
or:
  • All-in-one IFR navigator (GTN 650Xi or 750Xi) - new panel hole
  • ARINC 429 (GAD 29)
  • Audio panel (GMA 245R or similar)
Unless I am reading something wrong, all of the above can be achieved by simply swapping the single GDU G3X display with the new one. Likely simpler wiring, too. Am I missing something?

The only thing I don't like is: "If you have multiple G3X Touch displays they all need to be replaced with AXIS."

That's too bad :( Is this a temporary limitation, or will they never talk to each other?

The VP-X Pro is fully supported in AXIS.

The GMA 35C does not integrate directly with the AXIS displays at this time. AXIS Internal audio panel and GMA 245 variants are the only fully integrated audio panel devices. The internal intercom of GTR 205X(R) radios is also tightly integrated with AXIS.

Understood. thanks!

Apart from the fact that the audio panel function is available for the GMA35C, the system would still be compatible with NAV/COMs right? to tune frequencies from Axis display?

Only thing is that the audio selections would continue to be done on the GTN750Xi screen, right?
 
Are there any changes for the GARMIN PILOT to transfer flight plans to/from AXIS via Blue tooth or WIFI? to/from IPAD and/or ANDROID phone?
 
I was really hoping the VFR model would come with an audio panel/comm option. Oh well, guess I'll just have to settle on the nicer, bigger screen.
 
Congrats, now can you guys actually fix the Control Wheel Steering (CWS) function you broke on the G3X with firmware 2 years ago? Pretty please.
 
The integrated GAD29 is built into the GDU116C / NC versions, not the base model. If you are retaining the GTN and upgrading the EFIS from a GDU460 to a GDU116BX then you will keep the GAD29 but will still need to connect the GTN and transponder to the Axis display.
Thanks for chiming in.. can you clarify this section of the IM:

GDU 116 COM and NAV/COM display variants include built in ARINC 429 in/out ports. In this case, a
GAD 29 or GSU 73 is not required to interface with external navigators that require ARINC 429
connections with the AXIS displays in the system. However, a G5 in the system is not capable of receiving
ARINC 429 data provided directly to an AXIS display. To share external navigator ARINC 429 data with
both the AXIS display system and a connected G5, a GAD 29
or GSU 73 must be used.

It sounds like if you use a G5 backup, you'd have to have a GAD 29.

Or am I reading that wrong?

For an original G3X (non-Touch) display, you would only be able to repalce the display with an 8" AXIS display, which does not have an IFR GPS built into the display. You would need to modify the panel to accommodate one of the 11" displays to go this route. Besides the panel opening and mounting points, you are correct.

AXIS displays communicate with each other via HSDB, which neither the G3X or G3X Touch is capable of.


Thank you so much for your replies!!
Any plans to incorporate this down the road? Would be odd if not, I would think….

Yes, but I do not have an estimate for when this integration will be complete.

Understood. thanks!

Yes, GTN, GTN Xi, GNC 255, GNC 215, GNC 355, GTR Radios, SL30/40 can all be remotely tuned from the AXIS display. You would have to operate the audio channels (MIC selected COM, etc.) through the GTN Xi display however.

g3xpert,

Will the AXIS support the higher resolution terrain databases than what the Touch does?

Yes, the AXIS display uses 4.9arcsec terrain database, higher than G3X Touch.

Are there any changes for the GARMIN PILOT to transfer flight plans to/from AXIS via Blue tooth or WIFI? to/from IPAD and/or ANDROID phone?

No, You can transfer flight plans between AXIS and Garmin Pilot via Bluetooth. This is supported for any Garmin Pilot supported PED.

How about SmartCharts? is it already there in the Axis system? :)

We are in ongoing efforts to bring SmartCharts to our Flight Displays.

Thanks,

Justin

The purpose of including ARINC 429 from a HSDB connected navigator is to provide a backup path for External navigator navigation data, in the event that the primary display fails. G5 is not on the HSDB network. If the primary display fails, but your GTN Xi and G5 are still operating, you need the ARINC 429 datapaths to display navigation data from the GTN Xi on the G5.
 
First, thank you Garmin for continuing to make forward progress with a great product.

In the future, can Garmin champion its customer base in the experimental/homebuilt market and provide roadmaps for its model development with timelines? Please, please , please.

There is a group of builders (myself included), that are frustrated by the lack of transparency with Garmin's development timelines. I'm literally finishing up the final installation of a G3X system and I would have gladly waited a year or even more if I had know these developments were finally coming fruition. If i knew it was more like 3 years off or more, I would have stuck with going with a soon to be retired system as a guess. At least I would have made an informed decision.

I understand that providing a roadmap may be considered a give up to competitors and may be perceived as cannibalizing current sales/income, but if we are truly customers and partners in each other's success, communication would be a cornerstone. NOT being negative on progress, I'm just clear the lack of transparency may benefit Garmin in many ways, but there is a segment of the experimental market that you are definitively not partnering with as best you could to benefit the customer relationship.

G3x guy said you don't need the GAD29 with the Xi unit? I'm confused...

ARINC 429 via GAD 29 or GSU 73, is an optional but recommended backup path to include, if you have a G5 in the system alongside a GTN Xi, GPS 175, GNC 355, or GNX 375.

With the 'standard' dual GDU install and the Xi tied to both screens you really don't need the GAD correct?
Does the G5 still accept MAPMX?

Not sure how this will work in an RV-8. Need to get the tape measure out and see if I can fit it in with the required nav and com stuff.

At first glance I think it will. If the foot print is 11.6”.
Fits an existing G3X hole, thinking this might be an awesome option for the 8s given the space restrictions!

We will continue to sell G3X Touch displays and support new installations, including periodic software updates. We understand it is frustrating. The backend LRU's are largely unchanged, so upgrading from G3X Touch to AXIS Base displays is a relatively low burden from an installation standpoint.

If there were an unlikely failure of the HSDB network, the ARINC 429 > G5 path provides an alternate way for that information to be displayed to the pilot. You are correct however, there is a lot of redundancy built into a dual AXIS display installation, with GTN Xi connected directly to each display via HSDB.

Can I ask how does the G5 as a back up integrate into the Axis system? If the screen on the axis system were to go down what could the G5 handle?

Also, being off line most of the time at work, is there a PDF of the information about the Axis system available at all?

Besides the previously mentioned backup navigation data, the G5 will crossfill ADAHRS data in the case of a primary ADAHRS LRU failure.

In the case of a Primary AXIS display failure, the G5 can act as the display head for the GFC 500X autopilot.

@g3xpert Now that's out of the way - when can we expect software updates to the G3X Touch to fix things like:

1. TIS-B (TFR) not displaying.
2. User configurable Timer(s) (Egg, Start/Stop, Lap, Split.)
3. Enablement of Internal WAAS GPS engine to support IFR ops (LPV, L/VNAV, etc.)
 
Absolutely. We will have some great opportunities to get hands on experience with the AXIS equipment at Airventure 2026!

Hi Justin,
When can we expect the documents and features to be available? Should we expect all the functionality that currently exist on G3X to be also available on the AXIS? Will there be a list of new features that may not be available on G3X published?
 
Looks like a big upgrade! I will likely be buying 3 of them.

* Can a base model axis activate an approach on a gtn750? Is there any difference between a base model axis and a gtnxi and an ifr axis?
* Are there any rough edges with internal/external flight plan modes when using a base model axis with a gtnxi? just want one single flight plan across my panel with the ability to edit from gtn or axis with no friction between boxes and no mode changing or arbitrary restrictions.
* Is the bug fixed where the ground track pointer on the hsi is hidden behind the heading bug while the two are on top of each other?

The flight plan is synced across any variant of AXIS display, including Base models, and HSDB connected navigators, like the GTN 750 Xi. The flight plan can be modified from any display in the system, including the GTN Xi. An approach can be activated through the AXIS base display in this case. There is no friction between the boxes.

How does this fit into the subscription plans/prices?

The subscription prices are similar to the cost of databases for a system made up of G3X Touch displays and an External IFR Navigator.
 
Integration questions:
1) Will Axis support the WX500 lightning detector like the G3X did?
2) I have 2 x GA-37x antennas mounted. Can Axis use the GA-37 or GA-37x?
 
Not cheap but I just ordered a basic certified version for my 1949 A35 that is currently in the shop for an autopilot install at Aerotronics in Billings.

They had me at 13 minutes in the video and I was a hard no going in....lol.

Airplane already had a G3x and 650xi.....Oh well it's only money. I won't be replacing the 2 G3x's in my RV10 build for now.
 
The display pricing table is List Price. The price listed in each example is the Minimum Advertised Price. You will need to discuss pricing details more in depth with the Garmin dealer you order your equipment from.

Thanks,

Justin
Hi Justin - Are there any plans for a rebate program based on exchange of GDU 460/470’s for Axis?
 
I am working with my local Garmin shop to get two GDU 116BX and the needed G3x Touch to Axis upgrade kits ordered.
For the upgrade kit, I saw part number 010-14469-10 in the installation manual and that is what I asked the shop to order.

They came back stating that there a two different part numbers: 010-14469-10 for the B version and 010-14468-10 for the Bx in the Garmin system. The Bx one is only available in Q1 2027. @g3xpert which one is the correct one?
 
Would all the functions that currently available in GTN 650XI also be available in the 11NC model? What do I lose or gain in terms of functions between GTN XI and NC model?
