The Garmin GI 275. I needed to replace the Honeywell IN 825 EFIS In the Caravan and short of spending $50+K to put some multifunction (besides it already has one). I was stuffed. Most of the multifunction units cost even more to interface with most Bendix King autopilots. I have the KFC-225 installed and it actually works quite well, so not interested in replacing it. Also in something like the Caravan, you cannot use some of the cheap simple electronic displays, since it requires Cat 3 instruments (most aircraft over 6,000 lbs do). Putting it in was a snap, it just needed an ATI to 3 1/8 adaptor. It was able to re-use most of the wiring already installed for things like the magnetometer. It supports several different outputs and inputs. In mine it gets info from the GPS's, Stormscope radar altimeter, Multi-hazard awareness system (Traffic, EPGWS, and TAWS) and good old VOR/LOC/GS. Most of you will never need the multi-hazard, but it is mandated on turbines at least the TAWS is. The traffic is the type that actually interrogates and shows anything with a transponder, not just ADS-B.
So lots of stuff coming in. It outputs a bunch as well, headings to autopilot, Multi-Hazard, Stormscope and MFD and the ART-2000 radar. Quite a lot going on in a fairly tiny indicator. Small, but they managed to optimize the display, so it is essentially edge to edge and considerably more display space than the EFIS it replaced. The simple fact it can do Bendix King autopilots is a huge savings for most. Fairly straight forward to program, either on an offline tool, write to a USB stick and upload or use the on-screen programing screens. It does serval different logging operations, for the data obsessed, which will write to USB sticks. The resolution on the screen is way better than any of MFD displays I have toyed with, really sharp, bright and detailed. It better be, in the EHSI installed version it includes synthetic vision, which is surprisingly detailed.
Overall I like it. Easy to use and does way more than I could ask for and is bright and crisp. As I mentioned, install was very easy. Price, considering the options, was a real deal with labor. It talks to virtually everything. They have not been out very long and this was a first for my installer. So he had to be on the phone with Garmin a few times to get all the wizard boxes using the same magic. Not for everybody, but those of us working on the heavier side of backcountry needed something like this for quite some time. Big fancy displays also die big fancy deaths and cost tons of downtime to fix, making you little or no money in the process. So if your in the Twin Otter, Otter, Beaver, Porter, Caravan, Kodiak world, this works well for you and does not break the bank. Cheap enough to keep a spare on the shelf so you won't be waiting for Dorkco to turn around your box while you airplane sinks into the mud and you into bankruptcy.
