Replacing Dance with an RNS in a 2007 Roomster?

I'd like to swap the head unit in a Roomster Scout (2007) from a Dance to an RNS.

Possibly Columbus 510. Ideally I'd get navigation and DAB.

Is there anything I need to know?

What is "coding"?

Will it be compatible with maxidot and all other in-car systems?

I'm new to Skoda, so please don't assume I know what I'm talking about—I don't!

Cheers,

matt
