I've been using the same thumb drive to play music in my Pilot for a couple years. Recently when it gets to the last song on a given CD it repeats back to song one of that disk. Previously it would automatically advance to the next CD recorded on the thumb drive. I may have accidently hit a button (but don't recall doing so). The only thing I recently remember was a month or two ago I added the latest GPS data from a thumb drive. But I've done this twice before on an annual basis and the thumb drive advanced through all the recorded CD's. Can someone explain how to make the USB option go back to full auto-advance at the end of each CD? It comes in handy on long trips. Thanks.
