“USB Issues So i have been using this radio for a long time and never had an issue with it until today. for some reason when i go to usb mode it just says USB CHECKING and wont connect or anything. i have unplugged the usb cable thinking maybe it would say no usb connected or something and that didnt work, and then i restarted my iphone and turned the radio off and back on thinking maybe that was the issue and still nothing. then last check was the cable and that is perfectly fine. so my problem is the head unit. i dont know what to do with that do i need to disconnect my battery and let it reset or is it shot and i cant use usb anymore????? plz help any info would be appreciated”
