2010 LX570 usb not working. The icons on the radio are greyed out. I installed a brand new usb drive part number 86190- 60040 which matches the original usb drive. Did not fix it. Tried a different usb stick still not working. When I plug my phone charger into it i get a message on my phone that says check charger connection. Anyone know if there is a fuse for the usb. I don't see it on the fuse cover under the dash. Thanks
