Sorry if this has been covered before but it is complicated and I think I have used up my carbon allowance just searching google.
I recently fitted a 2004 Comand unit to my 05 CLK. After a fashion it all went well.
It does not play MP3's from a CD so I assumed that I need to upgrade the firmware but I cannot get into the Engineering menu to see what it is, so maybe the firmware has already been upgraded. I have tried every combination of buttons until my fingers hurt.
As this is a retrofit - and I haven't taken it to MB to get it coded as there is no real need - is there any way of telling what version it is running or what should I do next.
Thanks in advance
