5 Reasons I upgraded my Garmin 430 to the Avidyne IFD440

I have and always will be a huge fan of Garmin GPS units. I teach Garmin training classes and do 1-2-1 training all over the U.S. The 430/530 series in many ways brought ease of use in an affordable unit to general aviation. I think that the 430/530 series will be in service for many years. There are also five big reasons I am upgrading to the Avidyne IFD440.

Hybrid touch allows the user to combine the familiar buttons/knobs with the new touchscreen technology if they want to. The best parts of using an iPad, like dragging flight plan lines and pinch/zoom are built in. Unlike other touchscreen units though, you can use the screen or the knobs for every function without going through multiple menus to quickly access what you need.

Wi-Fi and Bluetooth are built in. The Avidyne IFD440 & 540 has both built in to every unit. This allows easy connectivity to popular iPad programs and at the same time lets you use a wireless keyboard! Yes, you read that right. Forget turning the knobs 100 times to enter a flight plan. Pull out the wireless keyboard and enter even complex flight plans much faster and easier.

Geo-Fill is one of the biggest step-ups to make flight plans easier and faster to enter. Every time I flied a flight plan from KLGB to SMO, the Santa Monica VOR, my trusty G430 always asks if I want the SMO VOR several hundred miles away in Mexico. It always adds just one more step to select the one, which is only 19 miles away. The Avidyne IFD440/540 has a logic chain built in that will always suggest the waypoint that is closest to your flight plan leg or present position. It seems like a small change, but it really makes flight planning much faster.

Radio communication is made easier. Decoding and display of radio names will reduce radio mistakes. It will be pretty hard to transmit on the wrong frequency when below the frequency it lists the name of the station displayed. For instance below 128.800 it will say Boston Twr. The system also allows easier standby tuning.

All of the above are great reasons to upgrade my unit, but the biggest reason is the instant upgrade. Avidyne calls it Plug N Play. I call it immediate gratification. Slide the G430 out, slide the IFD440 in, set-up 2 configuration pages and you’re done. When I installed the G430 my airplane was at the avionics shop for two weeks. When I install the IFD440 my airplane will be done in 10 minutes. OK, maybe 20, I will need to get some logbook entries and print out some supplements for my AFH. The Avidyne IFD 440/540 series are designed to use the same tray, wiring, connections and cables as the Garmin 430/530 series you are replacing. This makes the installation of every other touchscreen “upgrade” navcomm units seem slow and expensive.

As I stated in the beginning, I will always remain a fan of Garmin and the innovations that they have brought to make aviation better and safer. On the other hand, you may find me camped outside next to my mailbox waiting for my new awesome Avidyne IFD 440.  Is it here yet?? What do you look for when you upgrade your avionics? Let me know in the comments, and as always, fly safe!

  1. Can you use any Bluetooth keyboard? If so that would be awesome, if forced to another proprietary piece of hardware not so much.
    As well, is the remote software only for Windows? I love my Surface Pro, but its way to big for the cockpit for practical use. I love the size of the iPad mini for that and would switch in a heartbeat if ForeFlight was available on a smaller format Surface type device.

    • The bluetooth keyboard comes with the unit but you may be able to pair a different model. The application is for an iPad. I don’t believe ForeFlight, FlyQ will ever offer a “windows” version.

      Fly Safe,


  2. Good article, Gary, but I have heard some negative things about Avidyne service (“pull the unit and send it back to us; wait weeks for repair”), while I have personally experienced Garmin’s approach (“we’ll send you a replacement unit, then send us yours back; no downtime”). I upgraded the Skylane to GTN-750 and highly recommend; new firmware (6.11) now allows user-defined hold, and loading a 2nd approach automatically after Missed at first…

    • Garry,
      I’ve never had Garmin send me a loaner unit, they must love you more than me… I’m glad you like the GTN. The user defined hold feature is in every Avidyne unit as well. How long was your airplane down and do you remember what the installation cost for the GTN was?

      Fly Safe!
