Does not work
It just doesn't work... Unfortunately for me I realised it too late, because it's the cable for applecarplay and I was slow to install it. Until I realised that it didn't work, I tested it on a plug and in fact the phone didn't charge, which is why I couldn't get it to work in the car...
I strongly advise you not to use it, otherwise don't leave it lying around at home, test it and send it back quickly if ever.
I'm going to buy another one, I'm not happy about it.
