On the topic of retrofits I have the standard 2 zone air con on my F10 (520) and I was wondering if its possible to fit the extended 2 zone air con by just replacing the air con control panel?

or is there a lot more to it than that? Will it need software changes and other hardware changes?
Thanks,
