Voice Control Module VCM) and MOST Ring config... retrofit
The newly-installed Voice Control lever on the steering wheel DOES unmute the radio when pushed back (Voice Recog off) and the mic running into the VCM does work with the phone, so it's in the loop. Just not showing up on any of the COMAND System Screens nor activating for use.
Here is the MOST Loop order I have installed (as per MB MOST specs):
Sound out -> VCM -> UHI (phone) -> SDARS (Sat Radio) -> CDC (CD Changer) -> return
I installed VCM# 203-820-82-85, just as thrilos81 on this forum did in his CLK, so it SHOULD work.
Is it just needing coding? Or is there something else? (thrilos81 didn't need to have his coded...) Id like to save the Dealership $185 diagnostic fee to recode if not needed.
Thanks!
So pull the lever to wake it up and go for a nice drive. After restarting the car it should be functional. That's what I did with the R171 and worked a charm.
