Stereo FAILED to Continue Playing from USB Thumb Drive

[Ravenkeeper]

So last night, on my way home, my stock stereo worked as advertised, with the exception of not continuing from the playlist that I was listening to on my way to work.

 

Started heading to work, this afternoon, stereo booted up right where I had left it last night, EXCEPT it was NOT playing.  Tried pressing the play arrow, skipping back to the beginning/end of the song, thumbed through the media options ("iPod," "My Media Library," back to "Chris' Music" [my thumb drive], etc), still nothing.  It didn't start playing until I switched it to "RADIO," and back to "MEDIA." 

 

My other radio related issues have been it randomly rebooting after I had its memory reflashed for backup camera brightness issue, and the rare times where the skips would NOT work (steering wheel NOR on the touch screen on the radio).  Has not randomly rebooted since my last service visit, when I said something to my service rep.  They may have fixed that, while they were doing my oil and all.
