Just brought a black 1998 C230 home tonight .

I bought the factory changer on ebay and ordered a bracket from the dealer today. I was looking through the stereo manual tonight and it shows a picture of the changer in a cloth bag made out of the similar material as the trunk carperting. Does the bracket attach to the bag and the changer just sits in it or does the bracket attach to the changer. i am wondering if i have to call back the dealer to get the bag also.
