I asked this question in the general forum, but someone suggested I post it here too. My dad is considering buying a ZCP M3 but hates that the steering wheel doesn't have the radio control buttons. How hard is it to swap a multifunction steering wheel into a ZCP? Also, is it possible to map the sport button to something else on the steering wheel, like the talk button for the bluetooth perhaps? If this is all possible, is it DIY level?
