I have a 2016 Prius V with an audio question. I know I can play MP3 files directly from a USB thumb drive-that I verified this morning. One irritation is that even with only 50-60 files on the drive it takes the audio system several minutes to "examine" the files on the drive. Once that's done, however, I can find any file I put on the stick and play it. Works just fine. But what it will not do is to advance from one song to the next-when the tune ends, it simply repeats. I'm sure there's a solution to this. What is it? And yes, I know I could use my iPhone, but the Toyota interface is so clunky (my next car will have CarPlay!) and using a simple USB stick seems like a much simpler way to do things. Thanks in advance for the help! Fred in Oklahoma City.
