I know that we can push the knob near the cd slot to "mute" the system but....is it possible to completely switch it off?
I mean, no cd spinning, no radio etc.etc.?
Just a dumb question. <_<

NO
Just like you can't have the A/C fan stay completely OFF after switching the car off for a period of time.
Sometimes I wonder if BMW engineers have any comon sense.

Sorry, but how is it not "off"? The CD isn't spinning, so by any definition the "mute" function is "off".
I'm curious why it matters though. So what if the disc is spinning? Is it all about extra wear and tear on components? If so, then I understand, I guess...

I wonder that perhaps the CD data (digital) is stored in memory under certain conditions that would allow the CD to spin down and stop. Then if asked to restart it spins up and goes to the correct spot? Seems like if you switched to Radio or other source for a long time it would cause significant mechanical wear to simply remain spinning all the time. I'll have to check some other systems of mine and see what they do under similar circumstances.

Rudy it's not a "matter of matters", it's just curiosity :-))
I've never heard of an enetertainment system (home or car use) that doesn't allow you to switch it off.
The "mute" symbol just seemed to me that the system was not STOPPED but simply "muted".

"The life span of the entertainment system is much longer than the time a person uses the car, so why turn it off. That's just more complicated. Beside, we have designed a filter to the system to prevent/bypass spikes from engine start/stop. If the LCD burns out, replace it."
OK. All that doesn't make sense. It's not suppose to.

Depends . . . if it's a moving component, best to have it stop and start (to prevent wear). If the component heats, keep it running and provide a cool temperature (eg. you see light bulbs go out when you turn on the light, and zap). Most electronics have both. In any case, we don't have a choice in the e60. So there.

Spending about the last 40 years in radar, large computers, telemetry and other large instrumentation systems we developed some sound basis for leaving "High" power systems on 24/7 (365) to increase longevity. This included vacuum tube type systems and systems with klystrons, magnetrons, servo systems and the like. However, the lower the voltage and current and the more digital you got, then the delta came down to near equal failure rates. Usually mechanical systems like spinning hard drives, turntables, etc are rated with MTBF (Mean Time Between Failure) rates of 50,000 operating hours minimum and usually more. So we are talking of 6 years continuous operation rating for many of the audio drive systems were are talking about. And probably even longer on average.
