I believe you have to have the BE36 mod load last in the Community Folder - mine downloaded prefixed by Z as in Z-bonanza-g36-improvement-project.
Also you should retain the “workingtitle” prefix to the G1000 and G3000 mods.
Works fine on both BE36 and C172 1000 for me.
As for updates, not sure if there is a lot more that needs doing - although I’m no expert on the actual G1000 of course.
