So the old airspeed indicator serves as the "primary" airspeed reference which the GI-275 is configured for knots. The old DME antenna and cable for the KNS-80 was retained and repurposed as the UAT antenna for the Stratus. So our Stratus has an external GPS antenna mounted to the top of the plane and an external UAT antenna mounted to the bottom. All in all it's a very nice setup which gives us the latest generation of Garmin avionics and radios and relatively cheap vs GTN and glass panel options. The new JPI engine analyzer head now makes engine monitoring much easier and it's also right next to the ADI which makes it easier to scan.

The JPI on the left must be great for your back and neck! how long did it take to adapt to the gi 275s? Seems like lots of info in a small area while bouncing around in weather tia
For me it didn't take anytime at all, but I have a fair amount of experience flying behind various EFIS systems. Personally I like having a lot of information in a small area as your scan doesn't have to go very far and I find it easier to manage when getting bounced around. There's even an option to put the course and vertical deviation indicators on the ADI which puts just about everything you need for IFR within 3" of each other. The only thing I wish it had was a flight director. It actually does have that capability, but an AFCS is required and my autopilot doesn't have it.
Very nice. Those GI-275's work great as a pair, especially with the automatic redundancy. Can you slave off the GNC to do all kinds of groovy stuff on your AI and HSI?
It’s like comparing baby pictures but this is our 1962 C182E new panel. Flying has never been more accurate and precise.
So we got rid of everything except the old flap indicator and the JPI 930 we had installed with a new engine in 2019, we installed duel Dynon HDX 10” displays, new PSI 450b audio panel, Garmin 355 GPS, Garmin 255 Nav Com, all new electrical wiring through out the aircraft, pre wired for the Dynon Auto Pilot if it ever gets certified, and the entire panel structure required to be rebuilt to repair the old hack jobs done over the last 50 plus years. All in all it’s a dream to fly compared to the old six pack.
