W205 (c250d) retrofit | Rear camera | Folding mirrors | Android Auto

I just bought a 2017 c250d and just noticed the car doesn't have folding mirrors and rear camera. Quite disapointed about this...

I have command online system with 8,4 inches screen and I need some help with a few questions:
- Can I just buy a rear camera and plug it in the NTG box or I need those retrofit kits with an additional box to inject the signal?
- Does any of you did this retrofit? Where did you bought the components? Was it easy to do?
- About the folding mirrors, is there any retrofit for it?
- Does any of you installed a Android Auto retrofit? Does it work nice?
- Does any of this retrofits voids warranty?
Thank you very much guys!
command usually comes with backup camera.
it can be installed. just need wiring harness and camera. I have part numbers for both. then coding will be needed. are you in USA or Canada? if not, I can not help you code it.
folding mirrors can be coded in.
I can retrofit android auto/carplay as well. not cheap but possible.
it would void warranty on replaced items. but most likely they would still replace as they are all oem features.
