GTN750 in P3D

[navigator48]

I have purchased GTNxi for use in MSFS2020 and it works quite well although I don't seem to be able to set radio frequencies. I can xfer the frequency but after a couple of seconds the de-selected frequency comes back and it seems to be some random one with no association with where I am.

However, that's not the real reason for this thread. I also run P3D on my computer with the Flight1 version of the GTN750. I can't use that now because that version uses v2.7.1.0 of the Garmin Trainer and I've downloaded and installed the latest trainer (v3.0.1.0) to use with the TDS software. When I open the 750 in P3D I get a blank screen. I downloaded the appropriate version of the trainer but when I come to install it I see a message telling me I have to uninstall the version for TDS.

Is it possible to have both versions of the Garmin Trainer software installed to be able to run in the appropriate sim and where would the trainer for the Flight1 750 be installed, or have I now got to say a final goodbye to P3D?

Any help would be much appreciated.

Regards to all.

Hello,

The TDS GTNXi works with both PC Trainer versions: 2.7.1.0 and 3.0.1.0, so if you want to use other GTN software, we suggest only using version 2.7.1.0 of the PC Trainer.
Because of this, you will miss out on all the new and exciting features of version 3.0.1.0.

Unfortunately there is no way for both PC Trainers to reside at the same time.
Sorry that we can not provide a better response.

Unfortunately there is no way for both PC Trainers to reside at the same time.

It's actually possible to have them both installed and switch between which is active.
That's how I did it:

• If at any point a trainer asks to update or enable automatic updates, decline
  
• Start with all trainers uninstalled and to be safe delete %localappdata%\Garmin
  
• Install Trainer 2.7.1.0 with BOTH installation paths in the same root and subdirectory (replace [root] with the path you chose for all instructions), like:
  [root]\active\Trainers
  [root]\active\ProgramData\Trainers
  
• Only install the modules you need for 2.7.1.0 (eg GTN module but not GTNXi module)
  
• Copy the complete content of [root]\active into a new directory [root]\v2
  
• Uninstall the 2.7.1.0 Trainer. Also delete [root]\active to remove any missed files. Might need to again delete %localappdata%\Garmin (I wasn't getting the latest GTNXi module later if I didn't do that)
  
• Install Trainer 3.0.1.0 with both installation paths EXACTLY THE SAME as you chose for 2.7.1.0, like again:
  [root]\active\Trainers
  [root]\active\ProgramData\Trainers
  
• Again only install the modules you need from this trainer
  
• Rename [root]\active to [root]\v3
  
• In [root] create 2 batch files.
  
  1. v2.bat:
     @echo off
     
     if exist [root]\active\ (
       rd [root]\active
     )
     mklink /J [root]\active [root]\v2
     
  2. v3.bat:
     @echo off
     
     if exist [root]\active\ (
       rd [root]\active
     )
     mklink /J [root]\active [root]\v3
     
• You can now switch the active trainer version with the bat files.

Thank you for this option to swap trainers unfortunately everything went well except The V2 GTN750 can not find the databases in P3Dv4. When I run the Trainer It sees the databases. MSFS is fine. Here are some pic's of my problem this is P3dv4. Your  help is appreciated .

Thankyou very much for taking the time to reply to my enquiry and for the work involved. I have now got the unit to operate in both sims with v2.7.1.0 of the Trainer by selecting the appropriate option for which instrument to load. I must have had a brain-fart when I tried the first time!

Cheers
