Default G3X Software Update 12.20 (6/9/2021)

Hello,

We released G3X Software Version 12.20 to the Software Download Area today. Please note from the list shown below that many system LRU's have new software. After processing the update, go to the Device Information page on PFD1 and verify all LRU's successfully completed their respective software update before switching back to normal mode and verifying proper operation for the updated system.

There are a few frequently requested updates included in this revision, some of which were recently made available for G3X Touch systems, such as the transfer of fuel flow data to GTN (Xi) Navigators. Our primary mission is to increase the margin of safety for owners and operators of EAB aircraft, and we are very happy to also include a number of updates that improve system reliability and redundancy in this release.
  • One of the most frequently requested updates we have received is to allow fuel flow information to be sent from the G3X to an adjacent GTN (Xi) Series Navigator. This G3X software update will make this possible. Updated GTN (V6.71+) or GTN Xi (V20.12+) software is required for this to work. Once the GTN is updated, change the ARINC input on the GTN (that is receiving data from the GAD 29) from EFIS FORMAT 2 to GDU FORMAT 2. You will then be able to select Use Sensor Data on the GTN (Xi) Fuel Planning page. No configuration change is required on the G3X side. Fuel Remaining is also sent to the Navigator using this datapath.



  • GEA 24 P Lead RPM Sensing. 24.3.5.3 of the G3X Installation manual, revision AN provides specific installation guidance for this type of installation. A MOD 2 GEA 24 is required to make a direct connection from the GEA 24 to a P-lead for these purposes.

  • Provide DST data on GARMIN VHF NAV output, to an SL 30 NAV/COM. To enable display of this information on the SL-30, Press SEL while in NAV mode. Turn the large knob to the DST datalist. Press ENT to enable the display of DST data.



  • Improved redundancy in communication between transponder and GDU. A transponder communicates with the G3X system through a serial connection to the GSU 25. The GSU 25 typically already has a backup RS-232 datapath to the GDU in place for ADAHRS data redundancy purposes. In the event of a CAN bus failure, the transponder can now use that existing backup RS-232 datapath, providing GPS data to the GDU if the transponder is an internal GPS model, and making transponder remote control possible.

  • Further improved redundancy of transponder datapath. We now make possible an RS-232 connection from the transponder to a second GSU 25, in dual GSU 25 installations.

Change History:
  • Add fuel flow/quantity labels to EFIS/Airdata ARINC 429 output format
  • Add ability to control transponder via reversionary ADAHRS RS-232 connection and/or redundant RS-232 connections to multiple ADAHRS LRUs
  • Add support for RPM sensing via P-lead connection (requires GEA 24 Mod level 2)
  • Add DST data to VHF Nav/Com RS-232 output format
  • Add additional data to Text Out RS-232 output format
  • Add support for Rotax SCU 9iS FADEC interface
  • Improve audio alert output
  • Improve ARINC 429 output
  • Improve radio tuning RS-232 interface
  • Improve heading display when true direction is selected
  • Improve weather legend display of wind barb symbol
  • Change Rotax FADEC CAS alerts based on updated guidance from manufacturer
  • General improvements to system operation
  • Includes update to G5 software version 7.10
  • Includes update to GAD29 software version 3.40
  • Includes update to GEA24 software version 3.80
  • Includes update to GSA28 software version 4.90
  • Includes update to GSU25 software version 4.30
  • Includes update to GSU25C/D software version 2.60
  • Includes GAD13 software version 2.00
  • Includes GDL39 software version 4.91
  • Includes GI260 software version 2.80
  • Includes GMC507 software version 2.90
  • Includes GMU11 software version 2.10
  • Includes GPS20A software version 2.40
  • Includes GPS20A GPS software version 2.10
  • Includes GSU73 software version 3.80
  • Includes GSU73 IGRF database version 1.04 (Base Year 2020)

Thanks,

Justin

Thumbs down G3X Software 12.2

I sure hope Garmin has tested this version before the roll out. Version 12.1 caused errors on 3 different systems causing many hours of troubleshooting and reloading old software versions!!! I will not be installing for at least a year. Someone else can test it not me!

Standing by for a PIREP. Iíve held off going from 12.0 to 12.1 because of the issues noted above.

On the G3X Touch, to get the fuel data working, do you need to change the GTN ARINC input format?

If that was in a previous update, I missed it...

Thanks!

Ed

It's in the release notes -- change the ARINC input on the GTN (that is receiving data from the GAD 29) from EFIS FORMAT 2 to GDU FORMAT 2.

I missed it also -- what's not clear is what the G3X needs to be set to -- EFIS Format? 1, 2?? (Guessing EFIS Format 2)

Let us know how it works out. I am anxious to get the new sw, but also scared away by the reports last round.

I had to delete and renew my bluetooth connections after the last update for everything to work properly that way.

Ed, I think this update is just for non-touch G3X. Most current version for G3X Touch is still 8.81 according to the website.
