The USB port has never worked when attempting to charge my iPhone or another device. Dealer wanted me bring boat in, too much ordeal for this 72 year young grandmother. I’ve had my tech savvy grandson look at it, appears to be okay with wiring. I got under console & removed the USB port & wiring & tested on land power to see if port was defective. It’s okay & powered my phone. The other lights, gauges, etc are working. What next????
