Found this online as I need a new head unit, hope this helps anyone in the market. My mate tells me halford do price matching too, if you have issues with cac. I know some of my mates do. You can go to them and even have them fit it for you. Think you need a fascia, dab aerial and gateway to install. All can be grab from them except gateway.
