I'm an EE student at the University of Georgia who was assigned to a senior design project working on integrating the navigation app Waze with an existing Continental augmented reality heads-up display. Upon receiving the HUD unit from our Toyota sponsor my team decided to use the Continental mirror system (magnifies the LCD and projects to windshield) and the high powered back lit LCD while building a new control board.

We are having troubles connecting the 40 pin graphical LCD to a Raspberry Pi as none of us have experience with such a large LCD. Provided are some pictures. Anyone that could point us in the right direction would be great.

I think you need a driver to connect that LCD to a raspberry. Do you have the part number/reference of the LCD? For example,
I have yet to find a model number, but these are some codes I found on the LCD: 1A22 on the metal trim around the LCD and 8A186GHV 426335 on the ribbon cable. When I google any of these nothing significant comes up. I know that some hardware on the Continental control board was made "specific for Continental" and finding datasheets on this hardware is impossible.

We figured we would need a driver just not sure what kind. A little more about our LCD: it's graphical, seemingly unicolored, and 2" across diagonally.
