i will obviously need the surround to allow a single din to fit, but is there anything else? a cage or anything?

also which leads would i need in order to use the steering wheel controls?

the car has the 3 button controls, so half can, is it the same leads as a vec b for them to work or specific ones for a preface c? what about the aerial, is it a standard one or a fakra sytle one?

also when all fitted will i have any issues with getting power to it, as i have read about some not having a live, but all that i have read seems to be about facelifts, is that correct?

thanks in advance
