All AMG seats can be fitted with ventilation.

Looking at photos on the MBENZNL website and having worked with several mirror upgrades myself there maybe be a chance it is just a wood change. The wood needs to have the holes in it and I see to recall that the switches were held in place by screw posts with fasteners to tie them down.

The only way to know for sure is to remove the door planel. There are a number of things that changed in the 2006 model which were "presumed" in earlier models and no longer applied in 2006.
