This is a mod I've completed on my 2010 S550, although it will work on any car with an Aux In and 12v receptacle in the glove box. Big improvement in sound, easy, tool-less install and very affordable.

Here's a link to a PDF with instructions:

Very nice write up, I'm going to try this in my E55 as I always hate the sound quality while using pandora.
