Soooo funny. I done the exact same thing!! I totally forgot how to do it, spent bloody ages working it out. Hours went by with me being totally clueless and I too threw the leaflets out so just found out by sheer chance. The controller was sitting on my unit and I was just looking at it and seen the button on top and it clicked!!
Dont know how I forgot since I had only done it 3 weeks previously when I first got the 360!
