Likewise here. I will get in my car choose a playlist and be on my way to the mall and such and then when I feel like changing to another playlist, all of a sudden my screen becomes unresponsive. It is really frustrating to be experiencing this. If it is software related, I hope Pioneer is working on firmware fix of some type. I can go a couple of days trouble free, but then all of a sudden the next day I will have constant freezes to the point I want to punch the damn thing... -__-
