I have read all 133 posts of this thread and came to conclusion that:

1) [Only registered and activated users can see links. ] during first use.
2) The method to succesfully clone a protected SD card (virgin or popped) is not easily discovered, at least it is unknown at this point
2) Map file structure is somewhat different from other Garmin units and the method to unlock them is unknown at this point

Could somebody with better knowledge confirm that my conclusions are correct? Or even better, prove my conclusions wrong.

Now, having purchased a genuine Garmin Map Pilot from authorized MB dealer (haven't got the car yet, have to wait till May) I still have some questions. If someone with the card and the car could try and explain, is it possible (and how) to:

1) install and use speedcam POIs, for example Cyclops
2) install and use unlocked Garmin City Navigator maps

I'm asking because my MB dealer can't help me with speedcams and maps provided by Mercedes are outdated and updates are published very seldomly (they deliver 2015 cars with 2014 maps) and the updates are insanely priced.

Thanks in advance for any feedback.
