Pioneer Detachable Faceplate

Other Hardware Displays
1

I originally posted this in the project guidance section, but no answered it there. I am hope someone here will be able to help me. I have an old Pioneer detachable faceplate that I would like to use, but I am not sure how to wiring it up to my arduino uno or if it's even possible or not. I know I'll have to power the LCD externally because it's 13.v and display data comes across pin 3 because I was able to find the service manual and I have linking a few pages about the lcd driver and keyboard controller IC. I was wondering if someone could take look and see if they can help me wire it up.

Good luck. It looks like the controller is a custom part - that is, there is no datasheet for it out in the wild, so I would forget it, if I were you.
