Hello,
since yesterday I’m having issue with the command.
the screen is black and the radio turns on for 10sec then shuts off.
it does the same thing when I press the « on » button.
but yesterday after a 15min ride, the screen turned back on.
went to black later on and never turned back on.

has anyone ran into the same issue ?
i was thinking maybe a low voltage on a battery ?
witch one is in control of the command ?

2008 S550

thank you in advance !

 

likely hardware failure
believe it works without the screen so if the rest is shutting down - is it the comand unit beneath the heater buttons crashing out on high temp

 

Reboot COMAND. I do it in my 212 periodically. It's an old system.
