Hi all. I know this has been covered at lot but I thought it worthwhile passing on another UK option for getting Bluetooth connected to the NIT without the need for a preistalled CD changer. I fitted this yesterday and it work perfectly giving Bluetooth for music streaming, hand free phone, and USB charging all in one neat package. The name of the guy who sells them is Jason who is very helpful. This is the link for one that will fit the 4200. https://www.incarconnections.co.uk/fiat-bluetooth-adapter-streaming-and-calls/fiat-bluetooth-adapter-for-streaming-and-hands-free-calls-punto-multipla-doblo-sedici-ctafabt001.html
