I've got a new shape Focus supplied with a lovely Panasonic unit which does most things except make the tea. I tried DAB but it wasn't any better than FM and reception dropped out occasionally so I don't bother with it any more.
Ford dealers can do one for you. I've just found a text on my phone from my local dealer in Dec 2013 saying they could update the standard unit in my focus to a DAB for £179.
