Congrats. I got my 2016 a few weeks ago. Really nice ride isn't it.
I connect the iPhone to the USB, then play music stored in the cloud (via wifi, using cell data). I don't have any music directly on my phone. You can even access iTunes radio, and that will play through the UVO speakers. On UVO screen you'll see song information, but you will pretty much need to control everything (skip, FF, etc.) on the phone.
If I disconnect, and click media while on bluetooth, UVO starts to play whatever is the first song on my iTunes from "A" group. I cannot get UVO to play different songs this way. At some point, I will get a message pop up on UVO screen that says to restart phone and try again. Pandora is no better. Dunno, maybe my UVO needs a reset or something?
Uvo is actually controlling the functions just fine... I use itunes match, and when the phone is plugged in, i can play any of that music... skip songs, etc
though i have to unplug the phone if I want to use something like beats, or spotify.
no way to stream a spotify playlist and charge... at least using the front usb
I have had bluetooth sever the connection a couple times while i am in the middle of streaming...
but the wheel buttons work fine for skipping songs even in beats
Siri has been working good too, letting me send and read texts through the speakers
using the Siri button on the steering wheel
