Add Radio Controls to Wheel
 

Morning. I've seen a lot about keeping radio controls when I want to change stereo, but I have the opposite question. I want to keep the stock stereo (unless I can find the minidisc version), but add radio controls where my steering wheel currently has none.

Late 2003, 2.0 V6 Sport.

Any suggestions? I've found the part for the switches used, but I somehow imagine it's not as simple as all that.
