Hi, I've been looking around at some steering wheels and I wanted to know if anyone can shed some light into how difficult it is to change my stock 4 spoke steering wheel to a 3 spoke multi function mk 6 steering wheel. My car is a Passat b6 (07). The first image is how my steering wheel looks and the second image is the steering wheel i want. Is it just a matter of plug and play? Would I have to buy anything else?
