Switching radios: Navigation System to Business CD

Hello,

I have this weird radio unit in my Z4 Coupe (photo from the internet, but I have the same setup with no "big navigation"). I would like to switch it for the Business CD unit, so I can listen to CD's. At first I thought it will just be simple plug&play, but more I'm digging into this, the more I think it will need coding. I also don't have the 6 CD changer in my car.

I think my radio unit was EU only. Does anybody successfully switched from this head unit to the Business CD one?

Thank you.
