The Command in my 2009 CLS550 has "locked up" on playing media a few times.
Media in this case is discs and SD memory cards. When the unit it locked up, it won't load or eject a disc (message says "loading...please wait).
If I bring up the source list, it will play radio, but not discs or files on an SD card. I hear the disc mechanism moving...but the task of loading or ejecting does not complete.
I have tried turning the unit on and of and turning the car on and off. If I turn off the car and go away for a while (hours), when I return, all is well until the next time.
I am fluent in car and home audio and video....this is a strange one.
It goes to the dealer Wednesday, but they don't really know what to do.
It has happened several time and though not life threatening, it is a pain in the ***.
The car is under warranty....
Anyone else have a similar experience????
