Have you updated to the latest firmware?
Not yet. Still waiting for the link. I have, however, discovered that I can in fact access my Apple Music library and stream it to the car, but only if I turn the iPhone’s Cellular Data setting to “on”. However, I do not want to use my cell phone’s LTE 4G data for music streaming, as the phone has a limited data plan. I would like to be able to stream my Apple Music library through the adapter from the car’s Internet Wi-Fi hotspot, as the car has an unlimited data plan from a different carrier. For some reason, this does not work as it does when the phone is hardwired directly to the USB port.
