Garmin G3X Touch Software 8.70 Now Available 6/8/2020
We released G3X Touch Version 8.70 to the software download area today. Please note from the list at the bottom that many system LRU's have new software. After updating the software in the PFD1 with the SD card, the display will reset, and at that time it is best to hold down on the Menu button while it starts up in Configuration mode. Go to the System Information page on the PFD1 and watch all devices completing the software update before taking the PFD1 out of configuration mode and verifying proper operation for the updated system.
There are a number of new features included in this update, as well some behind the scenes improvements to improve system function and reliability.

So the Non touch guys are just forced to update equipment at this point?
I downloaded and installed this today, test flew for >1h this evening with no issues.
One note. If you are going to do the part:
"After updating the software in the PFD1 with the SD card, the display will reset, and at that time it is best to hold down on the Menu button while it starts up in Configuration mode."
Pay close attention on PFD1, as the PFD updates pretty quickly. I was doing something else and missed it. The rest of the updates to all of the LRUs probably took 20 minutes, and I wasn't really sure when they were done as I couldn't monitor in config mode.
Is there a way to get into config mode if you miss the initial reboot of the PFD?
Stopped talking to the GTX23
I did the update this morning. After reboot the transponder had a big RED X.
Called the G3Xpert line and after discussing the problem it looks like the new G3X software stopped communicating with the GTX 23 box. My latest GTX 23 software was from an Oshkosh visit to the Garmin Booth about 3 years ago. The new G3X software expects to see the latest software on the GTX23, as least that's the conclusion we came to.
As the current update doesn't pass CAN bus updates to the GTX23 the only way to get transponder software current is to remove and take to a shop. Currently waiting on them (local Garmin Dealer) to do the update and see if that fixes the issue. Can't fly with the Transponder out because of ADSB :-(
So if you have a GTX23 that's not current, best to wait to do the latest G3X update until you can update the GTX23 transponder.
GSU 25 Software
Can you power on your GDU in configuration mode and confirm that your GSU 25 successfully updated to software 4.10?
When is a new standalone G5 version going to come out? The latest experimental version on your website is 6.30 but the G3X update says it includes version 6.72.
I had the same issue with 23ES not working after installing updates. My 23ES software update was from 2019 Oshkosh.
Hanger Neighbor has the same issue with the 23ES after installing updates
Garmin been great to work with. They are going to call me back.
"Can you power on your GDU in configuration mode and confirm that your GSU 25 successfully updated to software 4.10?"
Checked my installation and the GSU25 software is 4.10.
