Garmin GPS175/GNC355/GNX375 Software Available For Download

[g3xpert]

We are happy to announce that we are making software updates for the 2? series of certified IFR navigators (GPS 175, GNC 355, and GNX 375) available in our EAB Software Download Area. The software can be downloaded directly from our website to an 8 GB SD card and loaded into any unit installed in a non-certified aircraft.

Anyone wanting to update the software for these units will want to first download Service Bulletin 2048 and review the software update process. After reviewing the service bulletin, download the software loader image, and create a software loader card for the update. There is only one software download, which includes the files required to update all 3 units listed above. The current download link will update the Main System Software to 3.10.

Please feel free to send any questions or concerns our way at G3Xpert@Garmin.com.

Thanks,

Justin

Maybe a comment in the next issue of Kitplanes will get Garmin's attention!

Much like asking FF "What's wrong with Andriod that you don't support it?"

Is there a change log? What are the changes?

Hi James,

The change log is listed in the Service Bulletin Document, but I have included below. The 2" Navigator series software was newly added to the support page in order to make available to the experimental market similar to the GTN series.


GPS 175/GNX 375/GNC 355 Main Software Version 3.10 contains the following changes:

• Adds support for additional FIS-B weather products:
◦ Turbulence
◦ Icing
◦ G-AIRMET
◦ Cloud Tops
◦ Lightning
◦ Center Weather Advisories
• Updates NEXRAD “No Coverage” overlay to be semi-transparent
• Adds support for database SYNC for transferring databases between Garmin displays – transfer
and receive from any GI 275, GPS 175, GNX 375, or GNC 355 and receive only from G500 TXi/
G600 TXi
• Improves availability for advisory guidance on LNAV approaches in areas without SBAS coverage
• Fixes a problem where GAE 12 calibration was limited to 6 points
• Adds Altitude Source Input Configuration setting to GPS 175 and GNC 355 to prevent nuisance
messages when connected to Sandel 3308/3500/4500
• Fixes an issue with GNC 355 carrier squelch setting. It is now applied when the value is changed
• Adds GI 275 support
• Adds Remote Radio Control Format 1 for GNC 355
• ARINC 429 labels are transmitted when in config mode


Great to see your panel project turn out beautifully!

BR,

Brad

Hello Brad,

Thanks for that! It's my first update and at first glance, I couldn't find the service bulletin.

I am so in love with this panel! Keep up the stellar work guys!

James,

There are two links in the software download area that begin with GPS175/GNC355/GNX375. One of them is the Service Bulletin Document, and the other is the software download itself.

Thanks,

Justin

Thanks Justin, hope you guys are staying safe and healthy!!

The service bulletin describes changes from v3.03 to v3.1. A unit we just updated hadn't been updated since it was installed and had v2.02. Are there change logs for releases between older versions available online anywhere?
