If we can have a way to for example choose which HDMI is used to output the result of a certain command we could use our Raspberry for the navigation as the main computer for all the screens in the van.

For example this way we could run a command to run Kodi (media center) on the main screen in the back which we then can use to view some Netflix.

Aplay command

aplay -l lists HDMI devices

Tvservice

tvservice -l lists HDMI devices

Displaying one of the attached USB cameras on the LCD display will be needed for reversing or for example for monitoring purposes while driving.

omxplayer seems to be a good solution.

Example

omxplayer -o local /opt/retropie/supplementary/splashscreen/retropie-2015-carbon-video-4x3.mp4

Use the Ford customer connection points to charge the auxiliary battery.

Bolts needed for using the connections:

• Print new custom cover with feed through holes for the wires

Try to get CAN bus sniffing working because this would make integrations with the car a lot easier without having to rewire things or cutting wires.
This should normally also give access to steering wheel controls for example.

• Candump

Adding a GPS module would make it possible to also use it for navigating when offline.
This could be handy especially with a van that you want to use to visit remote locations.

Check out GPS RTK for a very accurate way of determining the location. For the correct part of the GPS it will need a stream of data which will require connection.
Without it you could probably still use the devices as a regular (though expensive) way to determining longitude and latitude.

Made the switch from CrankShaft to OpenAuto Pro.
You have to pay a one-time fee for a license but it seems to run more stable and it uses Raspbian as OS which makes it easier to add stuff to the platform.

As a power source for the Raspberry Pi I will be using one of these fuse adapters which will feed this 5V power supply. I will then use regular USB cables to power the display and the Raspberry Pi.
I've used 2 separate cables for this because otherwise, I seem to get the under-voltage warning a lot in Raspbian.

For location of a good fuse to use:

• Ford Transit Custom documenation
• Ford Transit custom tech documentation

Way to extend the ribbon cable of the Raspberry pi camera module because we need to run a wire to the back of the van.
Something like this would be an option where we go from the ribbon cable to a normal HDMI port so we can buy a long normal HDMI cable and at the end of the cable we can go back to normal ribbon cable to plug it into the pi.

• Will the length of the cable be a problem?
• Find a solution like in the link above that is affordable

I have a GPIO button connected to GPIO 17 which triggers a system reboot using a python script.
It seems like when I plug in my phone to USB the device reboots.
This reboot seems to be triggered by the python service because when I disable it plugging in and out my phone doesn't seem to trigger a reboot anymore.

Maybe update the python service to write GPIO changes to a log file to see if there are other more stable GPIOs I can use for this.

Keep track of what changes I do to crankshaft so I can make some sort of install script to do all my modifications at once when I need to re-install everything.
