First of all, Happy New Year!!<br> I am writing now because I need step by step procedure for installing Mercedes original receiver unit. My car has Blaupunkt Cd player now, but I decided to put the original receiver into my car again. However, I don't know how to uninstall those unit and don't even know how to install the original unit. Can anyone tell me how to do them or can anyone know the site for this matter? In fact, the procedure of uninstalling the radio unit will be fine for now. I will figure out rest after I put away the current CD player... Well, I hope... Anyway, thanks for reading and have a greatest new year!!!!
