okay i am going crazy. I have downloaded this file five times. From the computer I say sent to the USB stick. I hit the stick to see the content and I see the file sitting by itself on the stick. I put it in the center counsel of the car and see all other files ( by the way is brand new stick) appear on the screen but not this upgrade file!!. what am I doing wrong. Does the file have to be brought into the stick in certain way??
