It seems that I can only charge my iPhone with the USB port closest to the passenger side and not the driver side. I havent had my car for long, so I was wondering what others have experienced. Thanks!
I am charging my iPhone 5 with the driver's side USB plug. You can try rebooting your center screen (push both scroll wheels together for a while). I have noticed that when the center screen reboots, the iPhone makes the bleep sound which indicates it's plugged in. So the USB power is controlled by the center screen processor.
Thanks araxara. I just rebooted and my iphone5 still wont charge in the driver side USB. Guess I will let service know.
