I've had my 2019 Silverado RST Double-cab about 4 months. I use the USB port and Apple maps regularly to get me where I'm going. The USB port worked fine this morning, and this evening when I got in the truck to go home, no dice. Nothing. The phone will still charge from the rear seat charger, and I think I got the blue tooth going, but no charge from the front seat USB port and no Apple Carplay. Is there a setting I need to find somewhere? Is there a dedicated fuse for this? Any help would be greatly appreciated.
