I grabbed the latest GNS 530 mod and it isn't working for me.  I tried the 172 and the Mooney and nada (none of the avionics come on in the 172).  Removing the mod brings up all the avionics, including the 430/530.

I'm sure there's something I'm doing wrong but I wanted to see if anybody else is having this issue?  

The latest version (currently 1.0.22) is at https://pms50.com/fs2020/gns530/pms50-gns530.zip

Yep, I'm an word not allowed!  I was using the wrong link on the Github.  Don't get old like me.  You'll forget just about everything!!!!!

Thanks @Phantoms

SOLVED.

I think Scorpion always uses the same name and link when he updates versions so that the link above is always the current version. The Github has old versions and work versions.

I was checking all the mods I use for updates after the MSFS update and that once I oopsed on.  I'll remember to use the link you provided (or actually read the Github page - hehehe).  He seems to do updates quite often which is awesome.  He's made the 430/530 a lot better for sure.  

There's a very active thread (over 1200 replies) on the official forums where the author of the mod post regularly and announces every update/change. It is definitely one of the most active mods in MSFS.

If you go to releases page in Github you will always get the latest also.
