Have had this car for a month or so now. I have tried several USB thumb drives formatted Fat32. the MP# player will only play one song over and over and over. The browse function is grayed out. When I try a different USB stick, I can browse and pick one song, afterwards, the browse function goes away again and the same song plays over and over. Is there an update that needs to be applied to this radio? I do not expect this from Toyota, this is terrible.
