No audio panel. That's actually the first on my list, because I don't have a panel mounted intercom either. A portable works, but i can do without the wires and "mess". I also like the idea of having Bluetooth connectivity through the intercom and not relying on the headsets.
I like the PS Engineering PAR200B, with the remote mounted Trig radio, obviously for space. So in the meantime, adding just that will give me an intercom, 2nd Radio, and audio panel in one install.
Next will likely be an engine monitor. I'd love to more easily control fuel flow, leaning, etc.
Looking at the photos, the CDI appears to be an ARC 525, from a fair amount of Google Lens searches.
After considering your input and advice, the MX300 will likely see out its better days as a COM, and horizontal NAV only. The money I will likely spend on 50 year old equipment and installation may not get me very far into newer avionics, but at I figured at least I'm not going backwards.
Next step will be replacing the MX300 with some sort of GPS NAV/COMM, or GPS COMM. Another one of your comments mentioned non GPS Approaches etc. We still have several around, but almost all are coupled with RNAVS. I can take the money it will cost to get a NAV Radio and put it toward another GI275 to eliminate steam gauges or engine gauges.
The Garmin 430/530 used market seems to be ideal for a stepping stone, and if i went with GI275, the HSI/CDI wouldn't need to be changed for a future upgrade. But by the time I get all these finances in line, the GNC355 and the GTN 650 will already be "yesterdays news". So who knows.
I really appreciate your input and advice. It really got me aligned before I through some money at a "quick fix".
I'm not sure who I'm kidding anyways, I have 3 daughters, aged 13,11, and 8. So i don't see Garmin having any large amount of my money anytime soon. HAHAHA
