Hi, i finally managed to get a Z yesterday so just settling down with it, but I have a new stereo I have to fit for it. I have spoken to Halfords and they have told me no fascias panel is required, i have the ISO harness adapter PC2-76-4 and the head unit. Will this got straight into the gap once i have removed existing radio? Does anyone know which harness is required for use of steering wheel control? Many thanks
