Thanks to everyone for this thread. I thought I was the only one with this issue.
The issue became unbearable earlier today after purchasing the Carenado Mooney. No avionics what so ever. I had intermittent problems before with the C172 and TBM, but I chalked that up to the most recent patch being buggy since the problems seemed to coincide with that update.. Pretty much the same intermittent behavior everyone here has reported. I'm a patient person. I get this is a large, evolving product. But after throwing down $30 for the Mooney, I was plenty displeased with no avionics at all. Flight plan or not, didn't matter. AI controlled start-up or manual. Cold and dark, or started on the runway. None of it mattered. No radios, no GPS - nada..
I've been running what I thought was a pretty plain install of MSFS. No real mods or fixes. But I did have two LIVERY packs I downloaded from FlighSim.com. They were for the TBM and the Savage Cub and they were installed by me into the Community folder. Decided to delete them to make the install as virgin a state as possible.
And voila! I got all the systems back for the Carenado Mooney. I have not tested it further, but it seems to be something to look into. How this impacts things like publicly developed liveries and such will be part of the process, for sure. We all need liveries and other items for the community to work without affecting the program base.
Again, this may not work for everyone, but it worked for me. Good luck...
