2007 ML500 Command Problems
Doing a bit of searching I found out the reason it doesn't work anymore is because I've cut the fibre optic cable leading to the bluetooth puck and since the fibre optic cable has components all connected in series, this causes the command unit to spot and error and switch itself off. I'm kicking myself in the back right now because of it. What a genius moment. How would I go about getting this fixed / bypassing the fibre optic lines? I know of a fibre optic loop adapter which does this but where do I connect it? Any other suggestions are very welcome. Thank you in advance.
Look at connector with a magnifying glass and look for the part #, e.g. xxx xxx xx xx so we may see if that harness is a separate one from the main harness.
my armrest was warnout and ugly so i got a pre-owned replacement.
I started to replace it the wires were in the way i could not unplug them to remove the armrest so i cut the wires replaced the armrest and conjoined the wires by twisting them and covered them with isolation tape. (it thought nothing bad could happen)

But when i started the car there was a message:
“battery protection: Convince functions temporary unavailable”
then waited a little bit and the radio didn’t start (only the mercedes logo was showing few seconds in command )
so here is mu question: did you maned to conjoin them (maybe I didn’t do it properly)
or did you replced the whole wires with the connector?
