Aftermarket Alpine System

Reading through this forum I realized that the K-wire must be removed if an aftermarket sound system is to be installed.
I have also found the VW TSB that relates to that - all models 1999 and after.
My questions is as follows:
Does the same thing need to be done for the 2002 model? My came with the stock radio/cassette not the new in-dash CD unit.
Does anyone know?
Thanks.
