Why can't I find this? 2007 c230 Full Range Stereo Signal Output

I've been searching forrrever looking for a thread detailing where I can find the full range stereo signal output from my radio, you know, the untouched, un EQ'd signal before amp?
Any ideas or threads I should be looking at?
Somebody has to have done this before and tapped into them for a processor integration with stock radio/cd control of somesort...right?
Thanks for all your help, and sorry for a potential thread repeat



The signal you are looking for only exists inside the DSP, as digital data, with no analog port output.
The short answer for people looking for a line level out, "Sowwry."
