Hello.. I wanted to replace the stereo in my 02 ml & have a double din clarion unit; wxz468rmp but not sure what adapters I need or if even possible. it currently has an audio 10 unit fitted with a double and single iso plug plus another that appears to contain 2 led lights, there is also a loose cable with small round female plug on the end? plus 2 aerial plugs? Have read things about having to replace the amp etc in order for this to work?
