Hi. G3000 v.0.7.6 and TBM Improvement Mod 0.6.1. I have CTD every time I try to turn the battery ON.
Do you have Navigraph charts in game? uninstall that option has help me reduce the battery switch CTD by 90%
I read somewhere else on these forums to use ALT+B to switch on the battery (so without touching the actual switch). That seems to help, I haven’t had a CTD since.
No, I don’t have Navigraph charts. ALT + B doesn’t work in my case. I’ve just tried it. CTD right after pressing ALT + B 
It’s strange because it usually crashes 2-3 times and then suddenly when I load FS for the next time (sometimes second time, sometimes third time) it works and switching the battery ON works fine. I think it’s something wrong with G3000 mod, because I tried without TBM Improvement mod and had CTD. Then tried without any mod and TBM worked ok.
Are you using the mouse scroll wheel to turn on the battery switch? If so, try just left clicking (legacy mode) the up arrow of the switch instead. For some strange reason this resolved the problem for me.
Ok, I gave up for now. ALT+ B doesn’t work. Left mouse clicking and/or mouse scroll the same effect (CTD). It’s just lottery. Sometimes I have several CTD, sometimes (the same settings, the same airport, the same time/livery) it works ok without CTD.
To be certain no other addon is interfering, would suggest only having the G3000 and TBM mods in community folder with absolutely nothing else. Try this with only the default basic livery and see if it works.
No, it doesn’t work
Empty Community folder (only G3000 mod). Default livery. Instant crash after switching battery to ON. I’ll try to reinstall FS, maybe it’ll help (I have the same installation from the date, the sim was launched).
It is a known WT G3000 issue.
try waiting half a minute before pressing “fly now” and start generator and some other switches before turning battery on.
might help reduce the amount of CTDs.
I just updated MSFS 2020 to 6. I noticed that this mod, the G3000 v075 is not being recognized.
When I launch the Longtitude, it still looks like the original avionics. I tried deleting and putting the MOD G3000 back into the Community folders. Is the G3000 mod compatible with U6?
Version 0.75 is not compatible. Version 0.76 is the latest, which is SU6 compatible.
This is not the WT G3000. It’s the stock. Like you were asked in the Longitude mod forum and here, are you sure you’re using the version 076a? I ask because we don’t have this issue. It’s working well for most of us.
My Community Folder was corrupt. I fixed that now I keep on getting that Lost Connection Every 5 minutes. I have a solid 900mbs internet connection and I turned photogrammetry off. Bing maps are on. I was fine until SU6. Anyone else seeing this?
There is any way to install the WT G3000 for the XBOX?
Do WT have plans to make a package like the one for the G1000 for the xbox marketplace?
Not currently, but they do plan to do a similar update to the G3000 after the G1000 NXi is complete. Patience. 
The title of the forum should be probably changed to “v0.7.6” since it’s the current version.
Waiting until the sim fully loads before pressing ‘Fly Now’ is a good tip…it allows for less issues.
I have a problem with USER and USR waypoints being inserted into the flight plan. I can’t delete them. Many times they mess up the TOD and VNAV prompts. Sometimes the system seems to have a mind of its own.
insert SID STAR Waypoints manually…
Inserting it via Proc messes up Flight plan
