After I pair my phone or tablet with the car via Bluetooth and play something (e.g. Youtube video), there's no audio anywhere. I'm guessing the car is supposed to be playing it. If I walk away beyond Bluetooth range, the Youtube video pauses, and when I start it again, the audio plays fine over the device. Go back to the car, it pauses, and when I start it again, there's no sound. I've told the device to share audio. Am I missing something?
