I have an Audiocontrol 4.1 equalizer (1/2 DIN size) from my old car that I was thinking of installing in that little strip of dash where the DSC button is. (see picture) The EQ is rated to be a 13-volt line driver, so I think it will work with the high-level output of the factory CD player. (yes, I expect to do some custom work to fit the unit in) Has anyone taken this part of the dash apart? Crutchfield had the instructions for my old car, but I doubt they would have it for the new 328Ci.
Any help would be appreciated...
