I was in the car the other day playing around in the engineering menu (getting the display to show AMG instead of the mercedes logo on startup), after about half an hour of driving just listening to the radio, the whole command APS unit turned itself off and back on. None of the right hand buttons work except for DVD which now shows a message saying 'no satellite radio' when you press it. You can't get into the service menu or the Map, it just doesn't do anything when you press them. Any ideas on how to completely reset the command aps? This is in an E55 w211.

Thanks

Paul.

 

Try this:

- Turn ignition on and power ON the head unit
- Press and hold the key combination 5+3+7 in this sequence for about 8 seconds to access variants menu
- Scroll up or down and select correct head unit variant, press OK to confirm
- Press the “Keybrd” soft key for the list of possible keyboard types
- Scroll up or down and select the correct head unit Keyboard
- Upon correcting the variant and keyboard settings, turn ignition off and ensure MOST and CAN asleep
- Turn ignition ON and check functionality of all keys using different applications

 

There is no way that I am aware of to "reset" the COMAND, but follow the instructions above to hopefully get it working again. It sounds like you have changed the Keyboard variant to something invalid.

 

I have a 2008 E350 Sport 4MATIC and I did the same thing but the outcome of mine was that the whole screen is blank after start up... so trying to revert back to original setting are impossible.... Do you guys have any solutions?
