I found part of my D2B M-B application list, but it is not prepared by M-B so accuracy is not assured.

It shows that all 1999 models except S & ML class have D2B and all 2000-2002 have D2B.

This does not make sense as my 2000 SL500 does NOT have D2B!

So, can't be sure at the moment of this accuracy.

You have to physically look at the input connectors as I had described.
