COMAND SYSTEM DOES NOT DISPLAY TIME w204
It happened the same day we all moved our clocks forward. Perhaps a Y2k for my C63's radio.Perhaps Not.
I was driving, then my radio cut out, the screen retreated, I said farewell; waited a moment, then powered the radio back on.
When I turned it back on, it seem a little different. I noticed the large analog clock was not shown under "system" nor did I even see an option to adjust time. You better believe I became habitually late to events too.
The radio also does not deceiver automatic Day/Night mode for the Map/radio display, nor will the buttons illuminate when my dashlights/headlights are turned on. (however the radio buttons will illuminate when manually selected in EMC TESTING in engineer mode..so I know they work.) I tricked the car.
Lastly, COMAND will not turn on/off with key ignition cycle...in fact while the car is running it will display the message (START ENGINE OR COMAND WILL TURN OFF IN 3 MINUTES BRO)
I found these codes within the radio, and subsequently still received no type of prize:
Audio/Radio, Speakers, and Nav work great. Nothing affected.
in engineer mode I found these error codes:
DTCc255 Lost com. with DISP_C
DTCc257Lost Com. with DISP_CTL
DTCd185 Lost Com with Turn/push (I believe this defines why comand wont turn on/off with key cycle.
DTCc020 B-CAN driver error

I don't know anything about the W204 in particular, but it seems that you may have a loose CANBUS wire connection. Probably the easiest/cheapest thing for you to try is to check that all connectors are pushed in solid, and for any kinks/broken wiring behind the head unit, amp and disk drive(s).
