Done it
Well, took it slowly, most of the day actually but I now have a 7" tft screen mounted in the headrest. I still have the other one to do, it's actually not to bad a job to do just each stage takes you further away from a complete headrest so can be quite nervy. Cable flows down through tube so it's a hidden install.
Anybody interested because if so I'll take loads of pictures tomo while I do the second one and do a write up afterwards.
Here's some pics to see, apologies for the quality, iPads not known for there camera prowess
