Octavia 2 pre facelift steering wheel retrofit

Hello.

Next week I'm buying a pre-facelift 2009 Octavia RS Combi MK2 with CEGA engine code.

Unfortunately, it has a steering wheel without multifunction. I've seen a few people who were able to solve the problem of getting a new multifunction heated steering wheel to work in the car, even an Octavia 4 RS steering wheel.

I've already dug into the topic a bit and I know that in addition to the new steering wheel I'll also need a new steering wheel controller, a new steering wheel slip ring, maybe new steering column switches and an extra cable for the steering wheel heating.

Unfortunately, I don't know yet what and how many parts I'll need. I also know that I'll need some extra module that will help the new parts work in the old car, but I don't know what that is.

Has anyone ever put an Octavia 3 RS or Octavia 4 RS steering wheel in a pre-facelift Octavia 2 car so that the multifunction and steering wheel heating work?

Can anyone help me with exactly what parts I should buy, what should be connected where, and what settings should be set in vcds?

Thanks in advance for your help.
