Loving the Bolt, after 4 days of owning it, but tonight on my way home I plugged in my phone to make a call and perhaps I did something "wrong", but the call said dialing but I couldn't hear anything thru the car speakers. Then I unplugged it and tried plugging it back in again. since then, no amount of plugging of unplugging or pushing Audio or any sort of sequence of button pushes and Mute/Unmute would get sound out of it. The car, that is. The app now says it's software is incompatible with the cars and it won't make a USB connection. Bluetooth sort of works - accept the sound.
Serious bummer.
