thought this may be of interest to some PCG-642-580-00 from Porsche is a 4 channel audio converter to MOST interface for about $119-$180. i have not confirmed as of yet that the MOST signal is the same between Mercedes and Porsche, but the generic Chinese made 2 channel MOST converters seem to all now be labeled to work for the W211 and Porsche Cayenne. similar 4 channel MOST converters run about $450-$700 from Russia. this adapter comes with the new Porsche Classic Android radios for Porsches. these units are manufactured in China. from the pinouts it looks like this MOST converter is powered directly from the speaker high signal this simplifying installation at least for Porsches.

i may pick up this MOST module to retrofit to my 2008 Cayenne, if so i'll most likely test it out for the W211. just thought i'd share with you all in case anyone was looking to try out something different.

Pinouts:
B1 = RR-
B2 = FR-
B3 = FL-
B4 = RL-
B5 = RR+
B6 = FR+
B7 = FL+
B8 = RL+

I’m interested to see how this works out

I'm interested to know how this works out as well.

Great find and hope it works out. I had the reg 2 channel in my G but doing a swap soon in my E and would love to have this.
