I would agree with that if everything was 100% working.
The DG needed to be replaced. So that was one G5 and I tossed in the other as I've had 6 vacuum failures in 5 years since I started flying 2 in while ifr. (Not all the same plane or owner just my bad luck to have the penny drop while I'm flying)
The EDM 730 came with the aircraft upgrading to a 900/930 is a want not a need for now and I'm scheduling for next years budget with a 650xi or what ever is coming out between now and then.
Maybe I'm just odd but I don't like the 440. The hardware is nice and it does everything the Garmin units do and cheaper. But every time I flew an aircraft with one it was always 10 seconds of thinking be for an action. With the GTN & GNS units my fingers just work.
