Hi all, I am about to have my plane go into the avionics shop for upgrades. I plan on taking out my Cessna ARC units and installing: 1. PS Engineering PMA-8000B Audio Panel 2. Garmin 430AW 3. Bendix King KX 155 4. Flightstream 210 Now, here's where I'd like some feedback... I was originally going to install a KI 206 for the 430AW, and a KI 209A for the KX 155. However, I found a reasonable price on a Garmin 106A and purchased it, so now I'm going to need to make some decisions on these other nav heads. Should I stick the KI 206 with my KX 155 (can you even do this?), or should I sell it and stick with the KI 209A? I'm learning as I go here. This is my first airplane and I haven't had it long, but I'm enjoying the learning process. Thanks for any feedback! As an aside, I have a Stratus ESG ADS-B transponder already installed, along with the ADS-B in solution they offer with it. In hindsight I probably should have gone with a Garmin 345, but I will say I do like the ESG quite a bit, and the flight logging is a cool feature of the Stratus 2S that I enjoy. If I had gone 345, would it have been able to utilized the 430AW's GA 35 antennae, or would it have had to have its own dedicated GPS source separate of the 430?
