For my initial attempt, I have used the WVGA (800×480) screen taken out of DTN-X680 GPS that I purchased online. Following instructions from https://garakutaen.sakura.ne.jp/index.html I created an adapter to connect the 30pin flat flex of the PC110 to the 40pin flat flex of the X680 display. I then used the CT65535 program from above to update the registers to switch over to the LCD. Generally it works, however I did not spend too much time on this yet as I want to more closely explore a closer matched screen I found (AT050TN22V1). There is a flickering which is not acceptable, I believe this is strictly related to the parameters used for timing / signal output on the ct65535 and not the quality of my wiring and could eventually be corrected. My main issue with this screen is the fact is the wrong aspect ratio and cannot take up the full display window.
The following is a gallery is my various attempts and failures:
