I had that issue with it as well, but I was using Google Play Music. I have a 2015 Infiniti Q50. To get it working I had to clear the cache from the device and Google Play Music and then restart the G6. Even then, it only worked for that car ride, once I got back in the car it did it again and I went through the same process. I returned the G6, I stream a lot on bluetooth audio and that is not something I want to do all the time especially with a phone that expensive. I never had this issue with my Pixel XL, Nexus 6P or Samsung Galaxy s7 with the same car
