I hope you don't mind me butting in but I picked up this thread as the ebay link earlier is to one of my adverts. I see a few people have asked about linking replacement stereos with the steering wheel controls. This is entirely possible for all C2/C3/C5 & C5 models if you are using either a Kenwood or Sony deck. The kit I can offer also drives the remote display and costs £75.00. If you are interested please drop me a line at simon@3foot.co.uk.
