Thought I'd put this in one place for people who are having the "missing databases" problem with the latest update to the GTN750. Actually it's in two places as I put it in the XPlane forum too.

1 - Uninstall the installed version of the trainer which will be 2.5

2 - Download this ... http://download.garmin.com/software/GarminTrainerSetup_2400.zip - it contains the 2.4 version of the trainers AND the databases.

3 - Extract all the files and run the setup program

That's it - the GTN should now work correctly

Thank you so much!  I just spent the last 3-4 hours trying to figure this out with reinstalling and trying anything that came to mind. I tried many searches to see if anyone figured it out and came across your post finally.  This is why I always hate updates.  I start thinking I'm just a dummy but sure enough there was really something wrong with the update.  Thanks again,  worked fine!

Hi,

there is nothing wrong with the update itself, instead, Garmin has decided to publish a new trainer update a couple days after we've published our own update, and our update was published to make it compatible with their previously released update a few weeks old only... It never happens usually.

@mykejb thank you for your assistance with this in the interim!

We've now released a new update which works with the latest (again) trainer!
