Adjust the volume on the phone itself to be higher to the point that you dont' have to turn the knob on the radio when. You switch from radio to streaming music from the phone. Just last week I thought my Bluetooth was going broken, but it turned out that my phone holder squeezed the volume down button to the point it turned the audio all the way down.I just bought 2017 Volt Premier with Bose system. I have noticed when going in high speed I need to adjust volume higher so I can hear the phone conversation but it taps out too soon needing more power. Has anyone seeing this as a problem?
