FWIW I have a Dynon auto pilot in my 1985 m20j and have had for a few years now (in Australia this is permitted using an engineering order). The dynon autopilot is a sensational. It has handled some horrible turbulence for extended periods without ever disconnecting. It flys approaches better than most autopilots (and i have used most of the common ones). Its accuracy is very very good. Hopefully the Dynon get the approval done soon - you will love it

I need the undercarriage switch if you still have it - the switch that your hand moves up and down ( not the squat switch or gear override)
