Well spotted, but I'm guessing that the windscreen actually is transparent and you can slip in a picture on a card behind it that will show up when you look right at the windscreen.

Look at the pictures that show all his accessories. To the left of the red display/storage panel is the radar dish, and below that is an object that has a pattern like the one that appears on Ironhide's chest. I think that object is a card that slides or is placed behind the windscreen in robot mode.
