2005 clk500
My 2005 clk500 stereo sound died.....checked all fuses & wiring to see if connected properly (for insulation falling off mainly, LOTS of components are suffering that now after 20 years) ....all good.
BUT my battery died so I put on a battery charger overnight....my stereo has sound now.
Go figure!!! LOL
So first try disconnecting the battery for awhile... you too may get lucky!!!

Removed and Replaced fuse 26, No Joy ( Left Side Dash )
Removed and Replaced fuse 64, No Joy ( Engine Compartment Driver Side )
Removed and Replaced fuse 20, No Joy ( Trunk Driver Side )

Thought about it for awhile then deduced the 11+ year old fuses may have too much resistance? In any case, I decided to put emory clothe to all of them.

Removed them all at the same time and polished with emory clothe, to insure Radio is in fact dead, I turned the car to acc. Gauge Display shows: "Radio ---" = DEAD.

Placed 64 first, 26 second then 20 last.

Wait for it..........................

Turned key to acc, We have SOUND :-) giggity giggity :-)

I wonder how long it will last but, if I have to do this twice a year, I can live with that or save up to change the entire system out for a bluetooth ready with navi unit. Who listens to CDs anymore, right?

This post was detailed enough to make sense and I was at the end of my rope chasing this audio issue down.
Performed the sequence mentioned with all new fuses, reconnected my battery charger as I've been working on this so long I've killed it many times over, and BAM - we have sound for the 1st time in almost a year. FYI - I was to the point of not caring and did all of it with the key in 2nd position. This restores my confidence in the 2009 CLK550 coupe - which has been a fantastic ride to own.
Now to fix the vlecrow affixed glove compartment, IR only keyless entry. and massive phantom power draw. Removal of that damn cd changer and looping off the optical comes 1st.

Thanks again to all here on MBWorld forums.
