HOW TO: COMAND update procedure and other controls
THIS IS FROM MB - FOR THE W220 when activating DVD player and TV tuner
==============================================
Applies to COMAND 2.5 (I tried it on 2.0 and it works)
- update comand with CD
- apply same update TWICE or more (good to reset custom logo to OEM)
- recover from crash or fail
- prevent ICAN loops during install (checking CD error)
1 Switch off ignition and withdraw ignition key.
2 Switch on operating unit with ON touch switch and wait about
10 s until operating unit is correctly switched off.
3 Press keys * and # at the same time and hold and switch on
unit with ON switch. Wait until download screenis displayed,
then release keys.
4 Insert download CD. (In the case of CD version with automatic
CD eject, CD is ejected and must be inserted
once again).
5 Press the following keys to override an older or same version:
First of all RET alone, then 2 and 3 (and 9) at the same time.
6 For download with ICAN activity (if ICAN active, download
stops endlessly in the case of checking CD) press keys 1 and 3
at the same time (before start of download!)
7 Start download by selecting with start operating unit rotary
knob and press on rotary knob.
8 The download now runs automatically in two stages and takes
about 45 minutes in total.
9 Confirm final message with OK, remove download CD and
insert NAVI map CD, switch unit off and on with ON switch.
Procedure in the case of download problems
=================================
If the download does not continue running or takes significantly more
than 45 minutes:
Remove fuse F61 (for radio/sound/COMAND operating unit and
navigation) and insert again. This fuse is located in the right below the rear seat bench in the footwell (fuse and relay box below right rear seat). The fuse box is enclosed with a black rectangular plastic cover and can easily be opened without a tool. A drawing of the fuse assignment is provided at the vehicle tool kit in the trunk above the spare wheel. F61 is the 5th, counting from the middle of the vehicle, and the 14th, counting from the door (long row of fuses with a total of 18 fuse positions, not all of which are fitted).
After this, once again start the download process.
