Re: BT Streaming Audio + Charge iPhone via USB at the same time?
Yes, both can work at the same time. The USB port in the center console is also an AUX input for the head unit. The head unit "assumes" that you want to use the AUX input when it detects a device on the USB port. Bluetooth streaming shouldn't be "disabled" by this. You simply need to select your phone as the input on the head unit. Yes, I know it's a bit of a pain.
I plug my iPhone into a USB port adapter in the DC outlet in the cubby at the base of the dashboard. This avoids any confusion in the head unit. It would be nice if the head unit would auto-detect my iPhone and begin playing music from it, though. I have to manually select it as the input every time I start the car.
