W211 GPS Antenna connectrors

Mercedes » E-Class » 2003-2009


I bought an original MB GPS/CTEL  Antenna code A211 820 55 75 to fit in my car.

There are 2 FAKRA connectors - One Black and One Violet .

GPS FAKRA color code is supposed to be blue.

So I am wondering which antenna connector is the GPS one ?

Thanks for your time and effort to help me
