the databases wont sync in my g3000. what should i do?

Hello, see if this applies to your airframe/software version: support.garmin.com/.../

That service advisory does not apply to my airframe. I fly a TBM-960 with software version 006-B4304-05. This has happened before and the last time the dealer didn't know how to fix it. Do I need to replace the GTC's? I feel like the databases should just "sync" on their own with no issues. This is becoming very frustrating. 

Here is an FAQ that provides guidance on how to sync your displays: Databases are not Syncing on G3000 or G5000

If your G3000 databases won’t sync, try these steps:

1. Verify Update Process: Ensure updates were correctly downloaded to the SD card or USB and are compatible with your G3000.
2. Check GTCs: Inspect Garmin Touch Controllers for communication issues or error messages.
3. Power Cycle: Shut down the aircraft’s electrical system and avionics, then restart.
4. Reinsert Media: Remove and reinsert the SD card or USB to ensure proper connection.
5. Contact Support: If issues persist, reach out to Garmin Aviation Support for further assistance.

With a TBM-960 running that software version, it’s reasonable to expect the databases to sync seamlessly without these issues. Replacing the GTCs seems like a drastic step unless it's confirmed as the root cause.

Try restarting the avionics and making sure your SD card or database drive is properly inserted and up-to-date if your G3000's databases won't sync. If the issue continues, re-download the database from Garmin’s flyGarmin site and re-install it.
