Put the graphicsboard back onto the display, fix it with one or two screws:

Attach all the cables.
Now after the front is prepared, it's time to look at the RF-input on the mainboard. Here you find the place of the internal connector plug:

We'll come to this later, but for now we just want to test!
So first we need an video-source. You can use any common reverse parking camera like this one:

But in fact it does not matter, because the ADV is capable of nearly any S-Video source (FBAS) you can provide. This could be a camera, camcorder, smartphone, PC, or whatever you have at hand. I use a VGA to S-Video converter attached to my laptop.
Because S-Video sources usually have a female yellow Cinch plug, i cut a common audio cable with male Cinch connectors in two and solder one side directly to the pads:

Then mount front and mainboard-parts, apply power and CAN-Bus to the quadlock. Use some device to send CAN messages at 125 kbit/s (MM-CAN). Here is my test-setup:

Then poweron the device and enter code (fun-fact: the video will be shown even if device is locked). Now send these CAN messages:
ID: 285, LEN: 3, DATA: 60 00 00, PERIOD: 125 ms => this is for "ignition on"
ID: 433, LEN: 8, DATA: 00 00 00 02 00 A0 00 00, PERIOD: 1000 ms => this is for "reverse gear set"
At this moment we should have a picutre... aaaand (drum roll) ...
