Look for the standard steering-column switch in the Porsche Electronic Parts Catalogue (PET). To
do this, activate the VIN filter in the PET2 .
Take note of the I-nos.
Replace the I-no. 9WC (Without Rear Seat Entertainment and without Mirrorlink) with the
I-no. 9WT (Mirrorlink/GAL).
If the VIN filter in the PET does not work, the standard steering-column switch must be identified based
on the I-no. in the vehicle information (PIWIS information system).
