I've had good luck with AUX inputs in the past -- both OEM and aftermarket. My new Car ('16 Chevy SS) is lacking one, and I really miss it. The '14s & '15s had one, but it was dropped in '16. Just my luck. Bluetooth is a total beatdown of inconsistency, latency, and signal compression. And the USB connection wants to take complete control of my iPhone, meaning I'm relegated to using the ridiculously slow and horribly-designed UI on the head-unit display. I'd much prefer to use the UI on the phone directly -- it may not be perfect, but it's vastly superior to the mess is MyLink. And if I don't like it, there are countless 3rd party music apps out there with a vast array of different features and UIs.
