Help !!!!!

Driving this morning and suddenly, I've lost my sat nav, radio, CD and telephone. There was a click through the speakers and the screen went off and then, came back with the Mercedes symbol.
After a short while, the warning regarding the comand system distraction text came on and then, the whole thing turned itself off again. This it continues to do.
Is it a fuse situation or relay fault ?

Sounds like the main headunit is fault to me.

If it was a fuse blown then it would not work at all.

I don't think it pulls enough power to warrant a relay either.

Try a long press on the power switch to turn it off and then try powering on again, or pull the fuse for a few minutes. This should hard reset it when you power it on. No promises but worth a try.

Thanks guys. I went out to the car last night and switch on the Comand unit and after a short time of the sat nav initializing itself, everything came back on. !
I can only assume that with all this wet weather, something got damp but, once left with a hot engine for a few hours, it dried out. That might sound strange but who knows ? Thanks once again.
