2007 s550 command module issue - no display
So is this the command module or voice command module or is it one in the same?

Display all of a sudden started flashing the mbz logo like it was trying to boot. As of now I only have AC controls and nothing else on the screen. Tried system reset (eject button) and disconnecting batteries for 15ish minutes, no luck. Dropping it off tomorrow at my Indy shop for repair unless it's an easier plug and play fix. Thanks guys

Sounds like a bad COMAND. Bummer. They're expensive. Hopefully your Indie can sort it out.

Is the command unit the same piece as the voice command module? Tried searching this issue and that's the only thing I can find on both mbz forums

The head unit/display seems fine. I'll get the mbz logo at times and the command safety warning. The ac controls are on there as well just no audio or nav functions

Get it in for a diagnostic. Sounds like the hard drive may be starting to fail.
