Default Concert Head Unit

Quick question that someone may be able to help.

The A2 is 2004 with a Concert II CD Head unit, I need to take it out to do the buttons (Soft paint problem!) and connect up an interface to it.

I do not have the code but I have read conflicting reports that the removal of the power will mean it needs the code.

Anyone have any experience?

I know for sure the RNS D in the S8 needs the code, but others suggested if its the same car the A2 with the Concert may be ok?
