The CNI5000 is a system primarily used in the Cessna Citation Jet (CJ). This system utilized a main panel faceplate assembly for all communication, navigation, and transponder units. The radios (w/o bezels) install from the rear of the assembly. Therefore, CNI5000 versions of the Silver Crown product line (i.e. KN-53 -04, KT-70 -1101, KT-71 -6101, KY-196A -50, KY-196B -0201) do not have a bezel so that the radios can be installed in a stand alone installation. Furthermore, the CNI5000 radios have 5 volt lighting.
