So I got a Nav VI for my 2017 GSA and I've hooked up my iPhone to it via Bluetooth. What I can't seem to do or find and answer anywhere is can you control your iPhone music with the wonder wheel or the Nav itself if you are listening through plain old headphones? All I want to be able to do is pause, next track or volume with my phone in my pocket. Will it only work with A2DP headphones?? Thinking it might not be an option.
