I have a KX-155 NAV/Comm for sale and the unit worked correctly including a bright display when removed from my airplane to install a GTN. It is a No ILS unit (VOR only). I will sell it for $1100 plus shipping. Here is a pic of the display. Note that the lens (can be replaced easily at low cost) has some delamination, but the displayed worked fine. I also have the tray, connector and VOR indicator that is also available.
