I am on the elderly side, so I am asking for your patience. Up until last week I was able to get my USB to work the last few years by unplugging it, waiitng 10 seconds, and plugging it back in. The USB icon would show up and I woud be fine for that day unless the car was off for more than an hour or so. Then the other day I got a message on the screen sayng the USB was no longer compatible, and it would no longer work. MY daughter and son-in-law work in IT and understand this stuff (goes right over my head). Could someone be so kind as to tell me step-by-step just what my daughter will need to do to get my songs from my computer (or existing USB) onto a USB that will work. Thank you in advance for your help.
