I had trouble with a flash drive, too many songs. Found a post that says no more than seven folders and two hundred and fifty five songs in a folder. Made a folder and put half my songs in it and left the other half out of the folder. So far it works. Hope this helps.I have a 2019 Renegade. I have an MP3 player that worked fine at first. Now I get a message that says USB error reconnect. Why would it stop working?
