95 S420 factory phone speakers?

[sixto]

Which speakers does the factory cell phone in a 95 S420 use? The stereo wiring diagram shows a mute signal from the cell phone but no audio signal.

Thanks,

Sixto,
I am told that the two speakers on the dash next to the A-Pillars are the phone speakers.

My manual also says the speakers by the A pillars.
