Not sure if this helps but here is what I did for mine.
Behind the steering wheel I simply replaced the BMW bit with a shiny chrome version.

The steering wheel wouldn't fit and I couldn't find anything that would fit so got a pair of metal discs made up. The one at the back bolted to the steering column and the on in front bolted through the steering wheel into the other piece. The wheel is bolted in place and sandwiched between the metal plates.
