I have a 2014 and retrofitted a usb charging coil which I ran to the usb connection in my console. It charges my Galaxy S8 fine but once you use it for Pandora or Waze, the phone gets an error message for slow charge. I wanted to try using a Samsung Fast Charge coil setup but was wondering if it would actually fast charge. I think I may need to hardwire it using a fast charge usb port. Has anyone tried this?
