W210 (E320) CD Changer questions

[Technique]

I have seen TWO brackets for the E-class (W210) CD changer. I was wondering if anyone here has the original MB changer with MB install kit actually installed in the FACTORY location. If so, can you please send me pictures of what it looks like installed? I have a few questions.

I have found the harness and have tested my cd changer. It works. I know that the changer goes inside the little "pocket" on the floor of the trunk on the driver side.

I have acquired a potpourri of brackets and MB logo dust covers but I want to know what comes in the factory install kit.

I can take pictures and send them to anyone who might be able to help me identify what needs to go where.

I know there are only two brackets made for this car and I have one of them for sure but it doesn't line up with the holes in the trunk. Which is the correct one?

Here is a picture of the bracket I have:



Here is a picture of the other E320 (W210) bracket:




Also, what is the point of this "soft case":



How would it be used in this installation? How would the cable get inside and how would the bracket mount if this soft case is used?

Is that "soft case" to be used with this "dust cover":



Any help sorting all these parts out is appreciated!

Thanks!
