BendixKing announced a modification to the CitationJet CNI 5000 using the KT-74 transponder and a remotely mounted WAAS GPS receiver. A package including the hardware, modified bezel, and STC will be available to authorized dealers. Please contact Southeast Aerospace to discuss ADS-B and upgrade options for the CitationJet.  See photo below. Alternatively, there are existing STCs that allow the installation of Garmin GTN navigators in the CNI 5000 location. The GTN can then control remote mounted GTX 3X5R transponders for ADS-B Out and In.
