Hello we bought our son an Ibiza 6L as first car year 2008. Since the old radio (Alana) was broken I bought a Pioneer DEH-S310BT.Incl connection set for Seat Ibiza 6l.https://www.amazon.de/…/ref=ppx_yo_dt_b_asin_image_o00_s00?… So that the steering wheel control goes again I ordered this interface.https://www.amazon.de/…/ref=ppx_yo_dt_b_asin_title_o01_s00?… So I thought that I had everything??? Now my question: Which cable comes out of the Radi o out and go into the blue AVC adapter??? I once hung a few pictures on it as I connected it. Do I need another cable?In the description this cable is shown with a jack plug!? On the radio 2 jack plugs go out. one is for the microphone and the other for the grounding?According to description.For what is the blue system Remoute Control? And where do I connect the blue for the antenna? I hope you can help me ??!!! Thank you very much Jörg
