My first post or two.
Was booking a recall service for my A class MFY 2018. The service department told me that my car can get a free Mercedes me adapter which makes my car a bit smarter.
Please refer the link for the details of the smart part.
I'm not too sure if it's limited to certain models or years. But worth to get one if it's free.
Enjoy!
Pointlessly limited in Australia. Not worth the effort even for free.
