Need the part code for the Honda Jazz 1.4 Sport Sat Nav/Double Din Radio Bezel, or recommend for nonHonda part

Buying a Honda Jazz 1.4 Sport and want to fit my existing double-din sat-nav. Will need a dash board modification which used to be available (even shown in the Honda catalogue) but do not have a part code to be able to order one.
Update: Unfortunately the Honda Main Dealer does not know of the code, even though there is a picture of the component in the car sales brochure and it is listed on the Honda Web site as a dealer fit option.

Would like the code or to find another way to fit my old Sat Nav to the new car.

THANKS!
