Fully integrated install in 2007 G35 - TheBasedDoge - 06-20-2020

Hi all, thought I would share my install now that I am pretty much done with it. My goal was to install OpenAuto in my G35 while still keeping the car looking 100% original and without loosing any functionality of the original displays. I was able to do this with a bit of help from a RGBS signal converter and a multi-input touchscreen display for the Pi. I also wanted to make sure my backup camera would still function through the car's original system.





Firstly, here is my car: Smile

Parts used:




· 7 Inch LCD w/ HDMI/VGA/2AV board - Must have PCB800099

· 7 Inch digitizer

· Weiya CV-04



o https://www.sintron.co.uk/products/s...converter-mame



· Raspberry Pi 4


· High current USB hub (I used an Anker 2 port 2.4a)


· Spare / used display unit to salvage OE display board from




Next, I had to modify a stock screen PCB so I could pull the signals for the backup camera and original screen interface (backup cam is composite, original screen needs to be converted from RGBS to composite)





Here is my prototype wiring:

The LCD driver I used has a very cool feature where it can switch to AV2 via 12v signal, so I wired this up to my reverse signal from the AV unit


AV1 – Stock Infiniti Interface


AV2 – Backup Camera


HDMI – Pi




This way, no matter what input I am on the screen will always switch back to the camera.




Next, i designed a 3D printed housing to hold everything and still sit into the stock location:

And then I fitted into my car:

For the Pi software, just OpenAuto pro 7. Still need to do the upgrade to 9. I also added a custom startup video. 


And that's it! looks factory and works much better. OpenAuto really makes my car feel modern again.




Future Improvements:


· Figure out how to get the climate control on the Pi.



· Figure out auto screen dimming.


- Hopefully figure out a way to get TPMS / CAN info on the Pi screen, anyone done this?










Any questions / suggestions for improvement please let me know Smile

Wait a second? You managed to display OEM radio over third party LCD? Did it required some additional module / converter?

I wonder if it would be possible with RNS-E

Yeah, It took some digging through the factory service manual but I figured out that the OEM radio uses RGBS HV signals for the display, so I used a converter to convert that into a composite signal for my new display. The converter is a Weiya CV-04 and is actually made for old arcade machines - but it turns out a lot of cars also use the same type of signal. I bet it would work on the Audi also, but you'd have to do some digging and see how the screen interfaces.

very clever! When most of us conceived this idea, we assume we can either use the pi screen to add on top of an existing display system, or we rip everything out and put a whole new system in place.
A hybrid sort of setup where you take the bits & pieces you want from your old system while hacking it to display on your pi screen is a really cool idea I never thought to try.
I'm sure this will inspire others to do something similar!

RE: Fully integrated install in 2007 G35 - TheBasedDoge - 06-22-2020

Yeah, that was my biggest goal with this project. I didn't want to lose ANY functionality, since there are still a few useful things I would need on the OEM display such as climate, settings, maintenance reminders, etc. This way I can take all that info and put it on a newer high res display.

If i can figure out a way to get some info over OBD / CAN onto the Pi screen like climate control, tpms etc that would be great, but I don't know how to do that yet.

Check out Rhys Morgan's posts about his jaguar. Lots of info and videos on youtube. Guys got his climate control available via an app he designed and integrated.

Nice work on your project!

RE: Fully integrated install in 2007 G35 - TheBasedDoge - 06-22-2020

Thanks, i will check it out. It would be cool to get all that data on the Pi so I don't need to switch back and forth as much.
