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.
