The ones I tried were new, of course still could be faulty. I went to the store and asked for one that would divide to both Apple lightning cable and USB-C, so my partner and I could both use it, since she has iPhone. The store owner said that he's not sure which ones will work, so he gave many different ones which we tried in the parking lot and then brought back. He gave us only one that spreads into 3 different connectors, USB-C, Lightning and the old Micro-USB. He said that this won't likely work. Rest of the cables were all either USB-C or lightning. However when trying, contrary to what he said, the 3 different connectors one worked, and it seemed to also have best quality, e.g. compared to one lightning which definitely had much worse performance. What I think is happening is that like someone said somewhere below as well, there's some difference in how fast or stable the data goes through the wire and something will change how they encode/decode it for those reasons. I don't know if it's the apps or the car software. I have to assume there's some sort of quality check and something will change depending on that. It doesn't help that packaging seems to list out random details and it's hard to compare cables with each other. Some USB cables have listed the data transfer rate, some have not, but they do allow data transfer. Then others don't.
