I am using the Just Flight Piper Archer iii in XPlane 12 and just installed TDS GTNXi.
When I click Power On in the Garmin Trainer Avionics Demos or Aircraft Trainers, everything seems to work fine there, but in XPlane when I do plugins > TDS GTNXi > GTNXi1 > Show Window the GTNXi750 window appears but is blank. Same for GTNXi2. My avionics are powered on (built-in GNS 530 is working).
I am using version 1.0.1.7 of the TDS GPS Manager.
Looking at the Garmin Aviation Trainer Launcher > Version Manager, I have version 3.10.3.0 of the Garmin Launcher (which was the version recommended by TDSGPSManager.exe), with version 21.3.7.0 of GTN Xi, version 20.42.2.0 of GTN Xi, and version 3.62.2.0 of TXi. I wasn't sure from the instructions if there were specific versions of GTN Xi I needed to install.
Oddly, after attempting a re-install, the TDS GPS manager is showing that GTNXI PC Trainer is Not Installed, with Available Version: 20.42.2, even though the Version Manager in the Garmin Launcher shows 20.42.2.0 as installed. Clicking Download and Install for GTNXI PC Trainer in TDS GPS Manager says to Please Select the Desired Component GTNXI Trainer, but the only active button available is the Back button. I don't think I was seeing this odd behavior in my initial install.
I did a quick check with several of the built-in XPlane 12 planes and saw the same behavior, so I'm thinking this is not specific to my Just Flight plane.
I'm kind of stuck at this point (despite being a software engineer!). I did try searching the forums; I tried reinstalls, reinstall as admin, etc. but might have missed something. Any other diagnostic suggestions?
Thanks!
