Glad to hear you are getting sorted.

I ran the wire up the windscreen/door post and then under the roof lining. The roof bit is dead easy, but the windscreen/door post was harder as I did not want to remove the plastic trim and damage it. I basically just pushed the wire under the trim with a plastic ruler.

PS the cable to the camera is pretty thick, run it in on a warm day it's a darn site easier than on a cold day..... as I found out. Ended up leaving the cable in the house on a radiator so it became more flexible.
