Dealer gave me loads of books and brochures, just not the one I need, and I only just realised. He reckons he doesn't have any others. I could take the van back... but for the sake of a handbook, it doesn't seem worth it. If I can find someone else with one I can make a copy and will be happy. (I'm very new to all this!)
To be honest, a lot of the control panels are in loads of different vans. If you stick a decent image up, someone is likely able to put you right till you get a book.
