First of all, your ride uses a single stage airbag system, and it will only accept a single stage steering.
There is a version of the older M Sport steering with bigger round airbag that could fit your car if you could find one.
Single stage steering have the slip ring on the steering itself, dual stage steering have the slip ring on the steering column.
The multifunction, its a bit hit and miss. Some car have it ready, just plug it in and it will work. Some car you would have to add some wires to make it work.
