yes I seen them do that, using a power bank, there are some videos on youtube about it.
I ran the cables. I pulled the A-pillar trim open.
In hindsight it is not necessary. Because I could not take the trim of. It seems stuck at the other piece of plastic, see at the yellow arrow (pic1). Maybe I need to pull harder.
But when you take out the rubber weather stripping you can put a piece of wire BEHIND the airbag and pull the cable through. I did not do that unfortunately. So now I can not push the trim back into place because of this clip. I will look at that later, the car will still work

My cables are behind the airbag so will not interfere.
If anyone knows in this 2026 Mk4 the pieces of plastic at the trim stuck together or can be taken apart let me know.
I just placed the power cable in the cigarette socket (pic2). The cable is behind the glove box. Still need to tie-wrap this in place. I ran the rear camera cable to the back but still need to figure out how to get it up to the window. Little break now

Bummer I could not get the A-pillar trim off.
The camera placement looks low but this is on the passenger side and in my case I can not see the camera when I am behind the wheel because the rearview mirror blocks the view.
