I have a 2013 Sorento with a basic UVO audio system. I prefer to listen to my flash drive (yes, it's all in mp3 format). It seems like when the car gets warm, the USB drive stops working. It will switch to the CD or Sirius and continue "loading" media files. Every few seconds, it'll flash back to the USB screen, then lose it all again.
Once in a while if I leave it do that for too long, it will "erase" files. They're not actually gone but it will only find say, 304 songs as opposed to the real number (well over 304) until I plug it into my computer again.
It also, while listening to CDs, will sometimes skip tracks. I will be halfway through a song and it'll just move onto the next. It's not a problem with the CDs as it does it to a lot of them and not often.
I have tried about 6 different flash drives (brands & storage sizes) and all of them do this. The dealer has also replaced the whole system once but it continues to happen. It has been happening since about Dec of 2012, shortly after I bought the car.
Anyone else experience any of this or have any possible solutions or ideas why it's doing this?
