You are bidding on a Bendix King KNS 80 Navigation System, P/N: 066-4008-00, Features: VOR/LOC/DME/RNAV/GS. It has been sitting on the shelf for sometime. It has a very clean and clear faceplate. It was removed during an avionics upgrade. It was working when removed, but I can not attest to whether it still works or not. One of the buttons was broken off while being stored as you can see in the pictures it is the faceplate of the button, the button is still there. I don't have the connectors, but it does come with the original tray. For sale as is. Thanks for looking and good luck bidding.
