I have a 2005 CL55amg. It did not come with the Phone cradle or phone but is set up for the phone. Does anyone know what cradle or phone it would take. I have att as my wireless carrier. I am trying to do this on the cheap.I don't use the phone much and don't need a bluethooth.I would like to get something off e bay but have no idea what phone or cradle would fit.Is there a way to tell?
