Hello, need some help with the installation of IGO8

EDIT: I came to a point where I got IGO8 started via the app menu. But it won't find any gps signal and it closes the app when the car restarts. Any help for these problems? 

To clear things up. (F320bt V.: 1.0000)
The steps I did: 
1. Changed the applib.dll to the modded one via testmode
2. I have put that app package on the sd card. 
3. Downloaded IGO8 + maps and copied it on the sd card. 
4. Made sure that the IGOlauncher uses the right path of the IGO8.exe (opened the .mscr data with notepad++ and edited the first shown path)
