For Sale is a NV-18GCP Display keypad for Grand Concerto or can be used with any G series Nuvo multi zone amp.  Comes with White trim ring which can be removed if you desire to change it to another color.  The Display is bright and without any loss of pixels.  This is one of the nicest used ones I have seen.  Great replacement for a dark E6GM system IF the system is running version 2.66 software or you upgrade it.
