Okay I finally got everything I need but I can't get the cd add on to read anything. I noticed that when I close it with a cd in it that it doesn't close flush. Can anyone tell me what the inside of the cd unit is supposed to look like. When I open mine there is a small gray circle in the middle which you place the cd on as well as the lens etc. Then on the top there is just this opening with a loose metal piece that I'm guessing is supposed to hold the cd in place as the lens reads it. If anyone could post some pictures of the inside of the cd unit or describe it that would be great.
