That's exactly what I'm doing, I am spending my free time to learn about this stuff, this is my first mercedes and I'm disappointed how this "premium" brand has all kinds of micro transactions and subscriptios. I am not paying 250eur to dealership for something that should be free like google maps are. On top of that, that stupid map is already outdated being 2022.
I've seen people talk about how that code is generated, but I am still not sure if the code itself is connected to some kind of database online, or that verification is done on HU...
Thus, as a developer I am looking into this stuff and so far my best bet is to just pay 50eur. Everyone just wants to make a few bucks on a shitty situation, fine.
So yes, I am looking for a solution, and I'm learning about it, so if you don't have any valuable information to share, or you don't intend to answer my questions I ask you not to comment at all.
