Hi, I have a 2014 ATS 2.0t luxury. I do not have the OnStar bluetooth, but I usually connect my phone via USB. I am having trouble being able to play my music (Spotify) through my car. I have an iPhone XR, but not sure if that makes a difference. When I plug my phone in, it will say that is is connected through bluetooth and I will press “media” on my car. However, when I go to play my music, either nothing will show up on the screen, or the song name will show up but nothing will play. In this case, my phone will say that the song is “playing”, but the screen in my car will say “0:00-0:00”. And to also mention, my friend has the same exact phone and plugged her phone in to see if it would work, and it immediately started playing her music. If anyone could help, it would be greatly appreciated.
