This morning I started to have this same problem. At first, it would not connect to CarPlay so I listened to the radio. Then, after turning the car off and back on it could tune to the radio stations but no sound from the speakers. The system is not recognizing that there is a USB device attached to it. Bluetooth connects but still... no audio! These constant issues are making me regret buying this car. Please help! I just brought it to the dealer last week to fix the "shift to park" issue many of us have experienced. They also had to update the software again so the check engine light would not keep coming in.
