Could the coding or flashing as they call it refer to the SA662 option?
So if you have a business CD, you need an update before you can fit.
I agree with Richd. I fitted one myself to my March build LCI (i have professional radio) and all was the same as the original instructions apart from the splice points. In no way do you touch the cars circuits. I work in IT and have never touched a car before. It wasn't that difficult.
If I was you, i'd have a go at it. Worst case scenario is you reverse what you have done and get a professional to do it?
