Ibiza headunit replacement advice

[Paulyb92]

Hi guys, been a while since ive posted. Need some advice... Ive decided to change my head unit in my car (12 plate FL FR). Ive bought a pioneer x700bt double din stereo and was just wondering if i need to purchase any wiring to accomodate this? Its got built in bluetooth and it comes with a microphone, my car doesnt have bluetooth but i do have the telephone button on my steering wheel stalk, is there any way i can wire this up to the stalk? Also is it a simple plug and play? will i still be able to adjust volume from the stalk or do i need to buy extra wiring? ... Also one last question, will my radio turn on and off with the car okay (dont want my radio staying on when i lock the car) or again is there some sort of wiring i need to purchase to make this work. Thanks in advance!
