Garmin GPS175/GNC355/GNX375 Software Available For Download

[Jpm757]

I downloaded the new software to my data card and installed it on my GNC355. When finished, I could not get the unit to power up in normal mode, it would stay in the configuration mode. Once I removed the data card the unit powered up normally. Apparently if you leave the data card in your unit without deleting the software update it wants to reinstall the update every time it is powered on. Up to this point I have always left my data card in the unit for safekeeping, however I would recommend either downloading the update on a separate data card or deleting the software update from the nav data card.

Jake,

Concur with your findings. Another VAF bubba at RTS downloaded the software update on a separate card, and we both used that card. While I was loading the software update in my 375, I downloaded a Nav Database update on the Garmin card, and when the software update was complete, shut down, swapped the cards, and re-started. Worked like a champ! So good call Jake. (And thanks Brian for the help!).

Cheers,
Bob

This is covered in the software bulletin document, Part II Step 11 and 12. As part of the software update process, the software loader card must be removed from the unit once the update is complete.

Thanks,

Update to 3.02:

• Corrected incompatibility issue with KI 208A and KI 209A.
• Corrected issue for GNX 375 with use of ?Generate ICAO from Tail? in config mode, so that use of this feature will now correctly calculate ICAO address.
• Added display of GPS Boot software version in Config mode.
• Changed default of user fields on the map to combined DTK/TRK (Desired Track / Track) in top
  right and DIS/BRG APT (Distance/Bearing from Destination Airport) in bottom right.

Update to 3.03:

• Fixes an issue where some traffic targets may be missed when over 200 targets
  are in range
• Fixes an issue where prioritization of selected traffic over
  non-selected traffic was not occurring. This could result in removal of selected traffic, if 60 or
  more other aircraft are closer than selected traffic
• Clarified AFMS completion instructions.
• Clarified installation instructions for aircraft without an avionics bus.

Thanks,

Justin

Justin--
Thanks for the link to the web page for these updates. Will you post the newest G5 (Experimental) software update on the same page when it becomes available?

I did the update on my GNX 375 earlier this week and everything tested fine after the update.Flew today and I have a message on the G3X transponder display that says ?Transponder Fault?. No error messages on the 375. Checked in with ATC and they reported reading fine for transponder and ADS-B. Any thoughts on cause of alert and how to fix?

Good Morning,

In configuration mode on the GDU, touch Transponder. There is a status box in the bottom left hand corner. What is displayed there?

Thanks,

Justin
