Androctonus1980

Hi,

my comand does not do anything anymore, it hangs up. I just see the mercedes star on the display.
Is there a way to do a hard reset or something?
The navigation dvd is inside but does not come out anymore... the buttons on the steering wheel do not work anymore.
Is there a way to reset?

I have a CLK 500 W209

Every help would be appreciated

or does anyone know which one is the fuse for the comand?

maybe I can do a hard reset like that... just unplugging the battery for a while did not help...
