1) with regard to the seat icon to the left of the clock - you cannot make that go away. Its part of the climate control system which shows you in what direction the air is blowing i.e towards your feet, your head or both.
2) The USB stick takes a while to load when first put in so might take a while to become highlighted. Keep it in place, don't remove it otherwise itll keep taking ages to load up. Once loaded and left in, it will be instant. If it doesn't work, pop it out and try the other USB socket and see if it works. If not, most likely to be the USB stick. Ive had trouble with a few which were intermittently loading but since replacement, its all good.
