When phone charger is plugged in, audio has no sound
My phone audio will play through the car speakers just fine. However, once I plug the phone charger in, the audio has no sound from the phone nor the car speakers. I’ve checked the mute button on the side and I’ve also checked to make sure the Bluetooth connection is still good. Once I unplug the phone from the charge port, it continues through the car speakers again. How do I make it still play??
