So, I've been using Bluetooth perfectly fine for playing music, and wanted to try out using a USB cable. I had a spare laying around and it worked perfectly fine when connecting my phone to a computer. So I took it to my car, plugged it in, and it does start charging the phone, but the screen says Connection Error. I am using a Samsung Galaxy S3 from T-Mobile, stock firmware, and have a ton of music on the internal memory, no SD card inserted. Any thoughts?
