I'm not 100% sure how it happened, but I noticed that the USB cable leading into the stereo was a little bit loose. I wiggled it around and looked through the opening where the fan is and noticed that the USB cable wasn't connected. It didn't look broken or anything, it just looks like it came unplugged from the motherboard. I got my unit 6-8 weeks ago. Should I try to just open it up and plug it in? Or should I try to go through Pioneer?
