I've got a 2013 ST wagon and it has the cruise control cluster fitted on the RHS of the steering wheel but there is no cluster fitted on the LHS. I have seen some images of the Ti model and it looks like it has a stereo control cluster on the LHS of the steering wheel. I am looking at doing a stereo upgrade and I assume that it would be possible for me to buy one of these stereo control clusters and retrofit it to the steering wheel and then get an appropriate adaptor to then hook it up to an aftermarket head unit.

Has anybody done this and if so how hard is it??
