GTX33 Remote Transponder which works with GTN 650/750 in your panel as the touchscreen control. $250. Price includes shipping to the lower 48.

Who Needs a GTX33: This is the cheapest way to make more room in your radio stack if you have or will have a GTN750/650.

Move the transponder out of the stack and mount it remotely. This transponder will work with your existing ADS-B just like your old transponder did... such a a GDL82, GDL-88, UAvionix TailBacon or Skybeacon, etc. It's just a reliable Mode S transponder that can be mounted remotely.

If you're trying to make room for a GTN750 instead of a GTN650 - here's your solution. If you're trying to replace a GNS530 with a GTN750 - here's your answer. If you're replacing a KX155 with a GTN650 - this is how you make more room.

I bought this transponder for a major panel upgrade with G600TXis, but later switched my plans. Priced here below what I paid, just trying to move it along to the next owner. It was removed by an avionics shop in Virginia. I am selling it exactly as I bought it here on BT, it has not been used or tested.

Includes tray and backplate as shown. Does not include any other parts or connectors.

price lowered to $250.
