Yep, we have to go to bashing BRP without even comprehending what the OP said. He ask specifically about plugging a thumb drive in and it not playing, nothing about BRP connect not working or speakers not working.
This is the only thing i do not like about a so called Spyder Lovers website, too many people ready and willing to find fault, even when it is not there, and bash BRP.
I have an idea, how about all of you that think the Spyder and BRP is the worst thing out thre, sell yours, buy somthing else, and go away.
