Dension Gateway Pro in Ibiza 6J SE250 factory radio

Hello. I have discovered the above adapter. On the manufacturer’s side my factory radio is specified as compatible. Only there is still a note that I don’t quite understand. Can someone enlighten me? “Steering wheel controls and MFA High Line cluster is required for phone. “So my 6J is from 2010 has no bluetooth and media-in factory installed. But I have this steering wheel remote control. On the radio I have one for CD-changers and Telefónica with the large connection (Quad-Lock?!) On the radio, however, this is not to be seen. (must be unlocked?) The steering wheel remote control is one without the telephone control.
