Momentary blackout
I've been flying with my G3x and GTN 625 for almost 2 years and enjoying the many features and benefits provided. I keep everything up to date with respect to software and charts. Something interesting happened yesterday after a few practice approaches. While taxiing in, the G3x went black momentarily then re-booted with all frequencies and screens as they were prior to the event. This happened once before exactly as described. Just goes black and immediately reboots back as it was. I never could find a reason and I am stumped still. I checked all connections carefully to be sure. I would hate to be driving an approach to mins and have this happen again. Anyone have a similar experience? Any suggestions?
Thanks,
David

David, strong suggestion is to contact Garmin - if it reboots due to a crash, could be HW, could be SW. Make sure that you are on the latest and greatest software, and ensure that the power to your system is reliable. I'm sure that they will walk you through to get it fixed, but I would not recommend flying it in anger until you're sure it's fixed.

A friend at my airport had the same thing happen last week, twice. Once in flight, in VMC fortunately, and once again while taxiing in. Just as you described with the G3X touch and GTN 650. Connectors were fine and power/grounds were checked. Bus power was fine during the event. No explanation.

Thanks for the reply. I promise not to fly in anger.

Yup, it happened to me once in vmc. That's why I have a G5!

Happened to me 2x right after the last database update. The G3xperts gave me a set of commands to use to download a file with the error to an SD card but I have not been to the hangar in 5 days to do that.
**update** After sending the error file it looks like I was not on the latest firmware of 6.3, hopefully that was the issue and all goes back to normal.

TeamX needs to hear about these events and they will likely want to see you logs and a special shutdown error file.

Yep
It has happened to me a few times. Always the left side. I wish I could say it was in VMC. I swapped the two screens and it still happens on the left side only. That leads me to think it may be power or ground related, at least in my case.
I have been working with G3Expert you will need to send a shutdown log as follows:
Procedure for collecting shutdown log on G3X Touch:
1. Insert an 8Gbyte or smaller SD card
2. Restart the PFD display in Diagnostic mode by holding down the NRST button during power up
3. Use Menu, Menu, Tools, Diagnostics to get to the diagnostics page.
4. Select Shutdown Log and then use the menu button to Save to SD card.
5. Email us the GarminError.xml file in the \debug folder on the SD card.

Thanks. I will do that this morning. Seems to be a common issue that needs to be addressed en masse by the G3xperts rather than one on one, as there are likely many more pilots with the same event experience.

Power issue
In my case, because it only happens on one side even when I swap the screens; it seems more likely the issue is within my wiring. With that said the G3X team has been very very helpful.
