Mercedes CLS 350 2013 model C218

Hello fellow Mercedes fans,

I am looking into some "do it yourself" fixing/updates/upgrade on my car but I find very little info on this specific model.

- I would like to update my comand system;

- Does the backseat fold and if yes, how;

- Most of the multicontour adjustments of the seats are not working, etc...

Where can I find info about these things. Is there a specific website or youtube channel I should follow?

Thank you for your time

All the best
