Alright, my 2019 or 2020 deal at Oshkosh or another time may be an audio panel upgrade. It may also be a Garmin 430W trade in and audio panel upgrade. It may be more (replacement of KX-165 if the faceplate keeps getting worse).
Aircraft: 1983 Mooney M20J Missile 300
Equipment: King Auto Pilot, Garmin 430W, GTX345 Transponder, KX165 COM/NAV 2, Aera 660 panel mounted screen receiving flow from 430W AND traffic/weather from GTX 345. Aera 660 also has emergency AHRS page. Normal steam six pack.
So audio panels: I have a King KMA24 from the factory. I have a separate signtronics intercom.
On the shelf I have a used Garmin GMA340. I was going to install this at some point, but I have recently flown with a Garmin GMA350 or whatever is in the 2018 Cirrus aircraft and really liked it (I also liked the playback feature so I can check back and see what a controller said). So now I'm thinking of buying that instead or doing a PS Engineering job.
-I know a swap of the KMA24 for the GMA340 does not work. You'd have to add wiring, change tray, probably replace wiring.
-I know there's a drop in same tray version of a PS Engineering system where you add new wiring that would replace the KMA24 and give me an intercom in one unit.
-I don't like the idea of doing two jobs, but maybe I replace the slide in option, do the wiring for the itercom hook up, and then wait until I do my larger job at some point in the future.
The idea was to have close to an all Garmin panel even though I do like outside technology. I went with a GTX345 as the base of my system instead of the Lynx, even though the Lynx has a real display. I plan to get a Garmin 750 in the end to replace my 430 (trade in at some point or private sale). For my #2 NAV/Com, I'll do something, haven't decided what yet.
That's why I was thinking Garmin 340 audio panel which is just sitting on my shelf at home. But after use of the 350, well, I'm not going to put the 340 in. So . . . PS Engineer, Garmin 350, do something in between, I'm still a few year out from the 750.
For the big job I'll rewire everything. For this smaller one, I may not unless you convince me to do so.
My sigtronics intercom can be touchy - it can sometimes cause some unwanted sounds if touched wrong. Sometimes the buttons on the KMA24 can cause static. It's fine for now, but they have both served the plane well it's entire life and my 7 years of ownership. Will do something at some point and I want to come up with a plan A, B, and C. It may be do nothing until the big job.
So give me ideas, spend my money for me, and help confuse me so in the end I make a good decision.
