Need to know the supported retrofits for Mercedes cars

[speed2134m]

Hi
Does anyone know how we can understand the supported retrofits for each Mercedes?
For example at the moment we have a 2012 E350 with this VIN: WDD2120591A589995
How can we get sure weather the car supports Night Vision & Seat Massager, cooler and heater Retrofits?

Please help

Thanks. I can see the present options of the car by Data Cards in WIS or by checking websites like https://www.datamb.com
But I wondered if I could find a way to understand the options which every mercedes does not have but can support by retrofits.
