Ebized, Impressed - Thanks for the info guys. I now at least know what part I'm missing and I know to check compatibility with the Irish model before I buy one
Stew, the car is a coupe but the dealership made no reference to it having BT. When we sat in it and saw the buttons on the steering wheel, we just assumed it was for that. It's such a common thing in cars these days that it never entered our heads that it might not be fitted - more fool us, I suppose. I will be giving the dealership a ring to confirm the part number for this model and whether the installation is the same.
Thanks everyone for the responses. I'll let you know what I find out.
