I'm caught in the cone of confusion regarding the best path to upgrade my plane and would like some counsel from my MS friends. I've read all these threads on avionics upgrades and I'd like some thoughts on my situation. My primary interest was in a EDM-900 while it was on sale this month. I was/am looking to do it right--CIES fuel sensors, carb temp probe, etc. Since my panel is all original my intent was to take care of the right side panel and remove the Garwin gauges, LORAN, ADF, RPM gauge, manifold and fuel pressure gauge as well. All told this is about a $9k project for this phase.
The reason I wanted the EDM 900 is that I have ~200 hrs on a remanufactured engine and I'd like to get as much life out of it as I can. I don't feel I get enough fidelity from the factory gauges to even let me lean it properly or even monitor CHTs.
We all saw the G3X touch was recently released. Additionally I've began my instrument training and feel I will "need" a navigator or a GPS solution of some sorts. Although there are many VOR and ILS airports nearby, my homedrome only has GPS based approaches (and a VOR/DME but I don't have DME). So the question is would I be better off in the long run doing a singular but larger upgrade that addresses ADS-B, PFD/MFD with integrated EIS and a GPS nav system? I have read the engine monitor discussion thread where @gsxrpilot comments strongly about the value of a dedicated engine monitor versus an integrated system buried behind menus.
Final comment, I am hoping to remain free from Garmin. I know it works but I'd like to have an inter-operable system that gives me some flexibility for whatever the future may hold. I'd do Dynon if it was certified (and relased), Avidyne or whatever else. Like many I'm hoping that the recent Garmin release will encourage more competition in this market versus run them out of business.
I look forward to your feedback!
