Carlos,
I am really (actually, EXTREMELY) curious to see how you are going to activate your CD player through yoour Volvo radio. Without being a mechanic, I doubt that you will be able to and I think that you will be wating your $$$ by buying that CD changer. All 2001 S/V40s have almost the same audio set up as the 2001 S60s, V70s and S80s, which needs software input/activation (for any changes) from the VADIS cart. And VADIS only has updates for Volvo units.
The prewiring is a $27 option but it has to be ordered WITH the car by the Volvo Retailer.
