We installed the Dynon to go with the D100 and also an AP74. True autopilot
functions with the Value button on AP74 serving as 3 different functions, 1. Baro press set, 2, heading bug set (push twice), 3 Altitude set (push 3rd time) and you can change both without using buttons on D100

We also coupled the Garmin 496 using the existing plug from the rear of the unit to access the "blue" wire for data into the pin #22 on rear of D100, so we also have course capability from the 496.
We also installed a 4 A CB & disconnect switch next to the D100 and have 0 issues with ease of shutting off. The stick grip is the reccommended location but I really did not want to open up that area unless something is broken and it isn't so I left it alone. You have the luxury/option of doing the stick switch during the build and I reccommend that highly.
Hope the info helps
