Hi,
i just purchased a 2017 Range Rover Discovery. In the center console is a 12 volt plug plus 2 SS USB ports. I have a cigarette lighter car charger in the 12 volt that charges my iPhone. When I plug the iPhone into one of the SS USB ports, the phone won’t charge but does play music from the phone and media center. Why won’t the SS USB also charge the phone? Am I only able to charge phone through the 12 volt adapter? I’m using a standard iPhone usb cord that came with the iPhone 6s. Thanks for the help!
