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.

If you were able to order code 357 with your Audio 20 System then it is very likely that you only need the SD card.

At least in the C-Class (not CLA) you can't order 357 without 522. I don't think there is a real technical difference between Audio20 with or without touchpad.
It's just the typical Mercedes Benz money making policy.

I think they will make Garmin Map Pilot the new standard, they started with C-Class / V-Class now also coming in the 2015 E-Class.

Very likely the SD cards will work for any of the new generation Audio 20.

BTW, I just checked if you select Garmin for the CLA you also need code 522 but it is only called Audio 20CD including Garmin preparation.
The Garmin System itself is called 357 as well. So I guess it's the same SD. But you have to have the new Audio 20.

That's correct. I hoped that a original card is enough. But now it's clearly that the individual CID from the SD will used for creating the files :-(

I hope that someone finds a developer, who can write a crack... Is this forum the right place for such a inquiry?
