Hi, I have created a thread on a combox retrofit. Thought i'd put a link here so other members outside of the UK might be able help.

This is the best guide I've ever seen for Combox retrofit. Once you've read it you'll be an expert. I still use it as a point of reference for retrofits I do now.

Agree that is a great guide. But it doesn't mention how to check if the CIC is on the correct firmware. How do I check this?
