I have a 2017 Skoda Fabia 3 and I’d like to retrofit a steering wheel with multifunction buttons that would fully work with my existing multimedia system. How complicated is this job, and is it actually possible considering that the current steering wheel has no buttons at all?

Possible but requires quite a lot of efforts, inlcuing probably exchange of integrated gateway / BCM module which is covered with Component Protection system.

It can be significant without much effort. Is there a possibility that some remote device would work with my Škoda?
