To anyone interested: to enter service mode<br><br>
of COMAND head unit, while in the radio<br><br>
reception mode, press simultaneously on<br><br>
'Mute' + '1' + '3' and hold for 5-8 seconds.<br><br>
<br><br>
Which version (and release date) your COMAND<br><br>
reports?<br><br>
Be careful.<br><br>
On the diag menu, errors list, you can press<br><br>
mute+1 and mute+4 to switch between two error<br><br>
lists, i don't know what the second one means.<br><br>
Pressing mute+0 will clear all the stored errors<br><br>
and i do not recommend that.<br><br>
