RXP GTN750 - Navdata an Terain data not found

Featured Replies

Hello,
I was using the RXP GTN750 with X-Plane 11 in 2020. I need to use it now on X-Plane 12 (I have changed computers since 2020). So I reinstalled it. Unfortunately it can't find any navigation or terrain data. So I can't use it.
Do you have any idea what I should do?

Did you install the Garmin Trainer?

Yes, the trainer is installed.
I was able to get the GTN750 to work with the various databases. It's OK now.

The problem there was:
When I had installed the RXP GTN750 on my old computer in 2020 with X-Plane 11, I had a particular installation configuration for the various elements of the RXP GTN750 (custom directories).
When I wanted to install it today in 2023 with X-Plane 12 and a new computer, the installer had used the configuration I had in 2020 (no doubt stored on their servers). Wanting a default installation, the installer refused to do this, even though I indicated that I wanted a default installation. The result was that the databases could not be found with the old configuration. 
I uninstalled the RXP GTN750 and redid the installation. This time the installer agreed to do a default installation in the choice of directories. This time the RXP GTN750 works correctly and finds the databases with a default installation.
