PS, here is picture of the antena - this one has wiring for phone, GPS and DAB

Comand Online Ltd :: Mercedes DAB retrofit kits :: W204/W212/W207 Gloss Black roof antenna (GSM/GPS/DAB)

It comes black, or colour to be sprayed. Silver may be available pre-sprayed although MB seem maybe not to make the pre-sprayed one any more.

[ps, from memory the blue double connector has the bluetooth and GPS antennas on W204]
