1. Unpack the file
   2. file 01_ETC_Diagnosetools copy to C:\
   3. file konfigurator copy to C:\Program Files\
   4. Run the konfigurator.exe and click on neu (new device)

Chose remote. through ediabas-konfigurator
Open itool-radar
Reserve your icom and look what your icom’s IP adress is there on itool-radar,
type the IP to the blank space under the “remote” selection on ediabas-konfigurator.
Open inpa, winkpf or any other bmw tools and enjoy!
