Have City spec can anyone tell me what is the plastic disc in front of the information screen for,there are pieces of card peeping out from it. it looks like I might be able to pull them out with some tweezers. Also anyone any idea what the gentle medium pitched fast spinning noise is from behind when the car is driven...... no problem just curious.
