I'm going to look at a Z4MC today. I suspect it may not have the DSP option I was hoping for. These cars are few and far between enough not to necessarily let this be a showstopper. However if its possible top retro fit this day from a car being broken, it could make my purchase decision easier.
So is it possible? Is all the wiring there? Is it just a case of buying the head unit and the amp?
