Because some of us actually only enjoy driving our JCW's more than being distracted by another screen/electronic gizmo that will be outdated long before the car! Don't knock the radio....it's perfectly fine when I even use it! Radio delete should be an option just like the rear seats! This car is simply an experiment.....something anybody can do! Looks like it does have back up sensors though (in the rear diffuser)..? makes no sense!but why have they put the std, non-visual boost stereo in there?
