Big drag. Spotify is already integrated into my Yamaha RX-A3040 HT Receiver, Echo, Echo Dots, etc. I guess I can at least stream from my phone over BT, but it's a shame the upgraded audio system won't receive as high fidelity a source. Could audio transfer from phone to car as a docked device, in which case it is hard wired into the car's AV system? Or, is the lightning connector just implemented a USB charging connection (no AV)?
