I have a 2004 CL55 and COMAND is showing the error message “Flash File System Damage…” displayed, head unit resets, no audio at startup until ignition is recycled, cannot navigate to a location saved using memory function, etc...issue.

I bought the update CD from MBUSA (220 589 05 22 00) to rectify this issue, per TSB. I tried to install it in the head unit as the instructions specify and the COMAND does not detect the service CD. It plays audio CDs just fine but does not go into the "detecting autonomous service disk...." dialog as it should when this service CD is installed.

Can any one offer any advice? Thanks in advance!

Some updates are intended to be placed in the navigation drive and not the head unit.

Since there are some USA differences I am working on the assumption that some USA cars in this year model are similar to the European design. Where the navigation drive is in the rear of the car.

If not then I would suspect strongly that you have also some deeper issue with the head unit regardless of the TSB.
