I am getting the Eurologics system fitted to my X5 next week. I contacted Eurologics who put me in contact with the UK distributor and by luck they are very close to where my wife's parents live.

I did find an in car audio specialist that could install screens in the headrests whilst keeping the active headrests but have decided to go with this system as it is more of a stand alone system and obviously in Holland enjoys a BMW warranty.

I think it's the best looking solution by far.
