Mercedes Command Unlock Codes HELP !!!!
My R171 is built March 2006 I have followed the instructions to unlock the command by first pressing audio then holding mute, phone and service for about 45 seconds but I dont get the 'Welcome to Engineering Mode'
What am I doing wrong ? Does ignition need to be on ?
Thanks in advance

Unlock Codes
Sorry for the question: What can you do if you unlock the "Command Codes" and can you undo any change?
