1998 E300 with Integrated Phone
 

I have the old integrated phone in my car. This is the version that is non-removable. I have a couple questions:

1) which speakers does it use? I know the w140 used to be the ones in the dash?

2) does anyone have a wiring diagram for the unit in the dash underneath the stereo?

I am going to wire in a bluetooth unit and would like to have an understanding of how the existing phone works.

My car does have the bose amp.

Thanks!

Thanks. I saw that on BenzWorld - that covers the stereo wiring diagram. Does anyone have a wiring diagram of the integrated cell phone unit in the dashboard?
