Hello all ,this is my first post ,I have learned a lot from this forum about retrofitting comand ,but few things are not quite clear to me. My car is 1998 w210. I am in process of installing MF steering wheel and the new style cluster. Anyone can explain what are the differences between can bus and non can bus comand /which are the can bus features that the other non CB unit doesn't have/ ? I want to be able to control the comand by the steering wheel. If I get a canbus comand as I understand I have to use a can bus simulator. But what if I use non can bus comand , the MF wheel is going to work with it ?
