    I have just purchased and took delivery of a UCI or Media Interface Kit for my W211 E Class, purchased from Comand online of course. I have found the Mercupgrades guide based on the W204 C Class, and i want to know is the process described identical to the installation on my car, is their a better guide. Any input and help would be much appreciated.
    FYI, i have the NTG2.5 Head Unit.

    Kind Regards,
    Christian

    Its pretty much identical, but some of the connectors change (the video cable that plugs into the back of the COMAND), and unless your W211 is MY09 onwards, you'll have to cut a hole for the glovebox connector. (MY09 onward is when it became a factory option)

    Thanks Richard,
    Ok so if i follow the guide and use my intuition i should not have any problems. My main concern is for power, where does it get it from? My car is a 2004 model with a retrofitted NTG2.5 Unit, so i will have to make some cuts but that's ok with me!

    Thanks Again,
    Christian

    Hi
    It needs a 7.5amp fused feed, but in reality uses very small amounts of current (under 1amp even when charging a iPhone). At the end of the dashboard under the end cover is a fuse box. Tap into a suitably fused supply there. Feed is permanent, as are all feeds in that fuse box

    Thanks again Richard,
    So cut and splice it into a 7.5amp fuse line?
    Will post results as soon as the install process is done!
    This will be fun!

    Kind Regards,
    Christian

    Yup, Dont forget the COMAND will need coding if you don't already have the Media Interface menu under Audio.

    We always strip/solder/insulate connections.

    Luckily my unit is precoded with the options as it's visible under audio :)! Thank you for your advice that was my plan also, factory look is my motto!
    Thank you so much for your help!
    You have made this retrofit a little easier for me!

    So the unit is in, but when I went to splice into the power I located what I was told A 7.5amp fuse, my old 6 stacker CD player, which uses a red wire! What do I do with the blue/black wire?

    Please help I want this done for tomorrow!!

    Kind Regards,
    Christian

    Aha

    As you have an old CD changer power lead, it has 3 wires

    brown (ground)
    red (poss red and another colour) +12v
    pink - wakeup

    Connect the brown to the brown, the power to the power, and the blue wakeup lead on the new wiring to the pink.

    If you can't find the CD power lead, then connect the brown to a suitable earth point, and the blue wakeup lead as described in the W204/W212 instructions on mercupgrades.com

    Thanks Richard,
    Ok so the lead Is the one behind the ashtray! I have seen those, I will try that and come back with the results!
    So now I don't have to splice the connector behind the fuse box?

    Yup - I didn't know you had a CDC before, that CDC power lead has all the cables you need and is fused perfectly.

    You may have to change one of the fibre end connectors to plug the fibres in (new smaller connector was with the kit) - look at the little arrows on the connectors to make sure you get it all the right way round, and don't forget to remove the little blue locking plastic part before releasing the other little clip that hold the fibre in place.

    Cheers

    Richard
