Sorry for asking , for what is this good ? I don't need a code to update a new map ?

This create on start in home/mnt/HBpersistence empty files called xxxxyyyy.swt where each xxxx are their meaning :
0017 - Voice control
0019 - Navigation Application
001B - Navigation Enabler
0028 - Europe Map Activation
002D - North America Map Activation
006F – Satellite Tuner
009B – Arabian Language
009C - BMW Apps

yyyy are Index mainly used for the ''28 or 2D'' or any other Map Update and done via the iDrive putting 20 digits. (see Fsc generator for map) given in the InfoMap.imp file and linked to the new Map using an Hex Editor.
SO if you definitively doesn't want to put a new code each time you do a Map Upgrade, while using Fsc Generator just put the index to the Max which is 00FF on the''yyyy''
Note that from factory this file is not on the Hdd but in the Flash EEPROM chip of the CiC.
