My fiance has a 2012 Cruze LT. She recently had her iPod stolen, so I bought her a 32 GB PNY thumb drive and put 25 GB of music on it for her. It worked great for one day. Now, when she tries to use it, it plays for about one minute before switching to the radio and alerts "No supported data found. You can safely disconnect the device. Done"
Now, we have been able to get it to index and work correctly on a few outings, but for the most part it behaves as above. Any suggestions? All files are .mp3 and it does have a folder hierarchy (artist > album > song) which works great when it works.
