Thanks Benny, I was looking at that but was concerned due to the name and price. "Unhook Deviation Assembly" seems an odd name!
183025 is for the US at £91.17, whereas 185384 is for the rest and only £64.63. It's making it even more tempting. As I live local I could even save on the postage by driving over.
I've used cruise on many of my current, previous and hire cars and find it extremely useful through average cameras, low speed limits, motorway cruising, etc. and had made a clear decision to myself to not have it on the Maserati. But the price, even with the VAT at under £80 and I could pop into Grimaldi and see what luxeries he has in, hmmmm!
