The Mercedes list also mentions C W206/S206/C206/A206 and S W222, but the table does not allow the GZCS F-4.0X to be assigned to their locations without further verification. The BMW list presents the GZCS BMW-CENTER as a separate reference for the center speaker: do not equate this location with the F-4.0X.
