absoloutes scrap part

I bought this unit for about 500 and am largely disappointed as in the description is not that it detects USB sticks and hard drives and this does also alledings I have a 64gb flash drive with about 35 folders in there and he realizes 95% of my folders tried to find out whether there is a system by which I have addressed myself to the folder but recognized that sees me really by accident from the one hand, it does not recognize the other he recognizes and therefore this is already a reason to scrap not to buy because I can yes I buy the same one without screen as man has nähmlich no folder overview
