My Hyundai Sonata came with a connector cord to iOS devices using a special 30-pin connector, which connects to USB & AUX (8mm headphone jack) input in the car. As you can see in this video, the regular Apple 30-pin to Lightning connector doesn't fully work - it charges but only lets you play music via Bluetooth, not via the AUX connection. But in another video we can see that there is a special 30-pin to Lightning adaptor, which also plugs into the audio jack - and which then does work.
Which is the right kind of adaptor to get? Can you identify the one in the video, or there another one that you would suggest?
