If you have an current shape pre Model Year 2009 A or B class with the Audio-5 head unit and want to install the Audio-20 (NTG2) or COMAND (DVD) system then you need this kit which consists of wiring, a new dash-board panel and some fibre optics. This is for the NTG2 systems (i.e NOT those with the built in bluetooth phone system introduced in late 2008/2009) or the older CD based COMAND systems. |
