    I did some investigation regarding the MapID.

    if you look at the folder structure under the NDS folder there are some .NDS files.
    These are SQLite Database files. Looking at them using a DB browser might be helpful.

    In root.nds there is a table called 'productDbTable'.

    The field 'DataModelVersion' could be the MapID, in my Europe 2014 (2.3) map version it is 6095.

    Maybe some could try to generate .unl files using that ID.

    I have uploaded a raw dump of my unused SD card to MEGA.
    Please keep in mind that at the moment there is no point of just downloading the image as we can not unlock for another SD Card (assumed CID lock).

    Please contact me for the link if you are interested to research.

    Although car Unit still shows 2.3.

    Just analyzed the update.

    28 files got updated 5 added.

    Updated files (28):
    Code:
    Please Login or Register to see the links
    added files (5)
    Code:
    Please Login or Register to see the links
    So this seems NOT to be a Map update, seems to be more like bug fixes and voice updates.

    I downloaded the untouched files from piotrscs (uploaded.to) by buying a 48 hour-Account. I have also a original card from MB buyed on ebay. This card was activated before, but i will try now if i copy the untouched files to the SD if it works. I hope that the all the well known CID from the original cards should work. I will post the results.

    As the *.unl from the uploaded card will not be the correct ones (not generated with the CID of your card) this will not work.

    From what we know so far when the card is inserted for the first time the *.gma and *.unl files will be read processed and then deleted
    Also the GarminDevice.xml will be created during that process.

    I assume that the *.unl files could be re-created with information from the GarminDevice.xml, however I have no Idea about the *.gma files.

    Somebody knows the difference between the Audio 20 CD and Audio 20 CD Touchpad version?

    Is it possible to use the audio 20 CD Touchpad on cars without touchpad?

    @piotrscs Is your version Audio 20 Cd, isn't it? According to the manual on the root directory of your copy, It seems the Audio 20 Cd version.

    The base Audio System is called Audio 20 USB.
    There is an enhanced Version available called Audio 20 with Touchpad ( Mercedes Dealer code 522 ).
    As the name suggest this unit has the touchpad functionality AND also some more wiring to connect the GPS antenna

    To be able to use the Garmin Navigation functionality you need:

    Garmin Map Pilot preparation ( Mercedes Dealer code 355 )
    which depends on Audio 20 with Touchpad ( Mercedes Dealer code 522 ).

    And of course

    The Garmin Map Pilot package ( Mercedes Dealer code 357 ),
    which in essence is the SD with the maps and the software functionality requires both.

    According to my MB Dealer Code 355 can be retrofitted if Code 522 is installed.

    Code 355 is the GPS Antenna and wiring which can only be connected to a Audio 20 with Touchpad unit (522).

    To safe some $$$ when ordering you should by package 355 and 522 and get an unused SD Card from Ebay.

    The owners manual on the SD card is specific to the Garmin functions which have the dependencies I mentioned above.

    In fact, I ordered my new cla class with audio CD with prewired system for garmin code 355.
    My first intention obviously is buy an unused sd card in order to save some money. But, on the Internet, there are many sd card, but all are Audio 20 CD touch pad version, and as you know the cla class do not have touchpad.
    For this reason, I was wondering if maybe the touchpad version can used only with the standard controller, in other words if this version is compatible with audio CD without touchpad.
    Although, at the first sight should not be because there are an especific version for cars without touchpad.
