I am preparing to route the wiring for a backup camera on my 2006 DB9. I think I will go above the headliner since I'm going to take it out and have it reglued. Is there any way passage into the truck from the back of the headliner?
I would be interested in other routes if anyone has suggestions.

 

FWIW, I did this on my Vantage, Likely not much of a difference, I mounted a video monitor rear view mirror and connected front and rear cams to it. I routed the video wire along the headliner gape and down the left side to the rear cubby where the Nav system sits. All the black box stuff in located there. It took about 30 minutes all together to rout the wire, once I had the rear view mirror and map light housing removed.
