Hi all, just to inform everyone, the ML's MCS Navigation radio plugs directly into the W140. No wiring harnesses, nothing. I was surprised getting it to work was so simple. I just plugged it into the existing harnesses and the unit turned on with the ignition key. The screen even dims with the headlight switch. I can tell that the speed signal is already there, because when I unplug the Nav antenna and drive around, it shows my movement on the screen.
However, getting it to physically fit is a bit more of a challenge. The W140 (1996-on) has two single DINs, the upper one for climate and the lower one for radio. I relocated the climate control to the lower DIN (the MCS couldn't go into the lower position because the motorized fold-down screen hits the shifter). For the upper section I unscrewed the single DIN plastic cage, and slide the MCS in. There was alot of plastic crap behind the upper DIN that I had to remove with a Dremel tool. I pushed all the wiring out of the way. But then I figured out a problem -- the MCS is slightly too deep, and it hits the wall in the back.
By any chance does anyone know what is behind that wall? I suspect that its where the cabin ventilation air flows...
Cheers
