Bus steering wheel on analog car

[Box1]

Hello,
Has anyone fitted a new multi button steering wheel to an older car ?
I'm trying to control a new radio head unit that is controllable from a interface unit that works with new wheels but not mine as mine is too old.
I know its not a plug and play thing but as the new wheel will only control the head unit and doesn't need to control the old car systems I thought there might be a way !!
thanks

Is your head unit wireless? Is the steering wheel wireless? Many(most?) steering wheel controlshave a "clock spring" wire loom in them that would be hard to put in a columb that uses the old style turn signal switch, that is where the clock spring would go. So if it is possible or not is up to your own skills.

The car has 4 buttons on the wheel but I've been told by lots of people not compatible with the new technology,
