Cazz, and others, this truly is a fantastic thread with some great photos etc. I finished mine (second attempt) in about 3 hours. Granted I was going slowly so as not to break anything and double checking everything before I soldered any connections etc.
The reason I purchased my 06 ZCP was because of this thread. I wanted the competition package, but I am one who also needs cruise control. Now I have both! I find it remarkable how powerful user forums are in regard to the knowledge, sharing, and value to owners. I am really surprised there aren't more manufactures (BMW) found supporting these sites?
Thanks again for everything, everyone!
