I was already trying myself and figured it out before you could react, but because its not really clear if you must remover those line on de SD/USB or my flash disk I was confused. but as of now everything except the primo run folder can be removed from my flash disk.
In the meantime I also stumbled upon the trouble with the BT and TMC and combined all the files, so far so good I think..
The maps I have running now too, I tried before but could be I had them in the wrong map or maybe it was the license.
Uhm today when I started it was doing the initializing again, twice..
