Hello everyone,
Just installed OAP on my 350z to replace my old GPS unit!
For this modification, I removed the old unit and re-used the housing to fit in the Raspberry Pi, USB hub, Relay Timer, Relay etc.
I even re-used the old connector to power everything to keep it as close as the stock one.
You can see on the image below that I removed all the old circuits, screen and screen protector but I kept the housing and the female connector.
I then drilled and made cutouts on it to fit the cables and hold everything tight.
Here is the compartment for the USB hub and the USB soundcard. You can also see the thin HDMI ribbon cable which was mandatory to fit in my car as it allows to have a small footprint on the screen connector which didn't fit in the car with a standard one. It also passes throught the case which is a plus !
To wire this up, I used the old connector as said above, which helps a lot to avoid adding wires in the car. And in addition, it is already fused and secured.
The difference between the old screen and the new touchscreen pushed me to design and 3d print an adapter (taking in account the width thickness of the old screen + old screen protector). As it is hidden behind the dash, I didn't take time to make something pretty, I just made it accurate, with various cutouts for cables, light for less material usage and strong to avoid any bending.
As the buck converter didn't fit inside the case, I bolt it on the outer case as there is just enough space inside the dash for it.
Finally, here it is in the car, before cleaning the wires and putting the central console back in.
I also made this modification to be able to connect a jack to the radio and have the sound of the Raspberry. In the future I must think of a way to ground it and get rid of the tape motors to remove any static noise.
----------------------------------------
I want to thank all the community for their help during all this project and especially jhornbr225 who took a lot of his time for me when I was struggling with my FRM01s (yes with a "s").
Speaking of this, I advise anyone who would like to build something similar to this system to take a FRM01 with RV20 written on it as mine. I bought 6 different FRM01 before finding one which behave as expected (function 10 not using T1 and counting in background). So save some time and don't play with luck on this !
If anyone wants the reference of the items I used, here is a list of it:
Cheers,
Shugi
