Got my Nava build for sale as per photo. https://i.imgur.com/8YXq9j4.jpeg Currently running 1.023 but I have a noise PCB (with components required to populate) and also the mux boards (if I can find them) to include in the sale so upgrade to latest FW should be possible.

Success! The issue was a broken connection between pin 14 on the display and pin 29 on the Atmega. I had tested these all before as per the diagram that KlangGenerator uploaded on here: http://i.imgur.com/V2nVr4Am.png And they all looked good. I did this several times!
