Are there other elements that determine is it possible to use STEERING AUDIO SWITCH?

(Sorry for CAPS names of the parts - took them from parts catalog and not sure are there other names for them)

Yes. The spiral cable ideally has more wires in it when the steering wheel controls are present, so the difference between those two part numbers is likely the presence of those extra wires.

I already know about that (mentioned that as an opening to my post and because I think that could be the reason why levvy coundn't make his switch work with radio).
I was asking "Are there other elements that determine is it possible to use STEERING AUDIO SWITCH?", because as I looked in parts catalog and service manual, I couldn't find any other parts associated with audio that had 2 versions (with SW support and without).

The only other thing that I am aware of, from researching it for the 2nd gen Yaris, is the different airbag cover. For the second gen, the Yaris without steering wheel controls have an airbag cover that is larger and that covers the space where the plastic piece with the switches would sit.
