Disklavier

Hi everyone!
I have upgraded my mpx1 with a DKC850 bought in Japan. The unit works fine and I have sucessfully  changed the language from Japanese to english ... 
But when I connect to internet services and select "d-radio" everything that comes after that is in japanese. So I m wondering if this is the case for other users with units bought in occident and if it is not, does anybody have an idea how I could fix this (I succeed in navigating through japanese menus but It is far from clear for me).  

Also on the yamaha musicsoft page for internet radio http://www.yamahamusicsoft.com/en/instrument/Disklavier/DKC-850/category/Piano+Radio/product/1204182?currency=USD  
one finds that there is at this moment 28 channels available and on my DKC the list (in japanese) seems to be only of  21...? Any lights on these matters ?
Thanks
