I have a 57 plate sline, with the double din concert headunit, I think its called the II+. I want to fit an AUX to it, it seems from a bit of research that this is fairly easy, plug three wires into the connector and enable with VCDS. I was just wondering if this cable would do the job, as it appears to have 3 wires and the Audi/VW oem aux point: KUFATEC GmbH & Co. KG - AUX IN Nachr�st-Set VW RNS 510, MFD2 (CD-Version) - Klinke 36891 if anyone could tell me either way I'd be very grateful. Cheers, Harry
