Lightbulb W220 Japan COMAND removal, Rest of World conversion

This is a complete recopy of the 3 part thread by MIROJ. This is being done to recover the invaluable pictures from the conversion process he documents. Recovery entails some sleight of hand thru the WayBack Machine so bear with me. Once completeed, have patience viewing, the images do load fairly slowly and MAY require an F5 tickle to move things along




W220 Japan removal, Rest of World conversion


Here is a photo record of my effort in restoring a Japanese w220 2002 model S500L to Australian, UK, SG ..... specification.

As required the modification requires upgrades in COMAND, Phone, CD, TV and Voice control wiring. The only thing that doesnt change at all is the BOSE wiring. This particular car is quite amazing as it has virtualy everything possible including a rear armrest phone and adjustable rear seats.

Japanese trunk




Here is a Japan specification trunk with the cover removed. You see the TV, Teleaid, Navigation drive and 10 stacker CD player with BOSE right down the bottom.





Here is the reason why the head units will not swap directly. The bottom half of the Japan unit is missing since it is in the trunk.







The UK / Euro unit is completely self contained. So you can see that now the first problem is half of the head unit wiring is in the trunk




This is the set of cables from the trunk for the old equipment.




To install the replacement cables my suggestion is that you make some room inside the car and open up the cabling trays to allow for the new wiring to be installed and the old wiring to be removed.







Trace the power lines back to the fuse box for anything that is no longer needed.





After removing all of the wires no longer needed and tracing individual wires that seem to go nowhere, install the new wires fresh from the factory.



Installed wiring (all same specification as same year RHD car).
* Optical cable
* Navigation
* Voice control
* CD changer
* Phone
* TV

Some wires are specific for the rear parcel shelf as they relate to connections for phone, gps and TV and need to cross over to the other side of the car for connections to be made



The rear trunk area now ready for the replacement equipment. Notice the coloured tape markers for location matching. This is how the cables are located so that they are not in the wrong position. The car has about 30 or so colour-coded junction markers.




Now in place with prewire for TV




The trunk is now in the new specification with the correct CD stacker and trunk lining. The interior is back in one piece. Due to some other unrelated work the centre console will be done later and some update photos included.




It takes 1.5 days with 2 guys working on the car. The labour was in fact the lowest component of the job. The wiring and control modules were somewhat more.

Resolving the speed signal component (two wires to front control unit).



Speed wires in place




The right hand side deals with connections for the GPS and GSM signals. Because the car had teleaid which is not needed now there is a spare phone connection for the glass mounted antennas which means that the bumper mounted system no longer needs to be activated but can easily be done if necessary.



Antenna junction point for GSM and GPS.

The old phone was in the rear armrest. The front armrest will be refitted with a phone system (UHI) and Bluetooth will be possible with the correct Nokia or Siemens phone.



The armrest is loaded with phone and TV cabling as per factory spec.



Phone system in place and operational with COMAND. Bluetooth and UHI in place even though the car is pre-UHI build.



FM radio working correctly.



GPS and all other functions operating normally. SRS coding removed for Teleaid.

Thanks, Ex-Fed. I tried that with Wayback Machine earlier to day, but was not successful. I'll put this in the Audio & Telematic stickies. It might be a good addition to the W220 S-Class Encyclopedia, as well.

He didn't upload pics, they were hosted on his personal web page. Using Firefox and EDIT mode, caught the embedded URL and used that to prime the WayBack machine rather than the thread URL
