After more tinkering, I got the navigation program running now. But I'm running into two problems.
1. Whenver I hard-reset, the autorunce.exe is executed and tries to reinstall the unlocker. How can I make it so that it just run the winCE and not ask to reinstall? Do I have to delete the autorunce.exe or mnavdce.zip out of the SD card? I also lose the IGO8 installation whenever I hard-reset.
2. I'm not getting any satellite connection. Can someone share their sys.txt? I'm assuming something wrong in my sys.txt
