All W221 come with Telephone armrest prewiring.
Still I was not able to connect my iPhone 7. Do I need a new HFP software update of Viseeo 4?

@Christian
what you mean by connect?
make fone calls or stream music?
in my w221 it connect with my 7plus without problem once bluetooth is on in iphone and in car you just need authorize it by code during pairing and calls works, phonebook etc
music streaming is other story
standard comand don't support it in w221 you need to use multimedia interface in glovebox and connect there bluetooth adapter either merc genuine (hard to buy) or something like bluetooth receiver with mini jack output then you can stream music wirelessly (by use AUX as source)
it works in mine car
often is!Just a simple Google search
These instructions suggest 62872 for the code
