dont want to here it lol, just here to help.
usb cables can be tricky, you may have to set your HU to statt looking for it, it may not be automatic like on your computer, the simplest, cheepest way to connect your ipod, is to use the a male/male head phone jack, but you cant control the i pod from the head unit, other cables you can but they can get $$$, and idk if the touch has anything to do with it.
