Will share a couple of photos of my new dashboard (need 4 more posts...). New instruments are 2 x Garmin GI275, GTN650 plus an engine monitor Insight G2. It took a long time to get approval from EASA and it is even not done! At least if one of you plans to install such instruments part of the paper work is done.
I don't know Badin-Crouzet (autopilot isn't it?). Mine is a Century III, not recent but probably easier to maintain than the Badin-Crouzet.
