On the PC Miler unit, the directories where the navigation app and maps are, are corrupted. Like with the RightWay the built in shell allows redirecting the navigation app launch to any WinCE executable. Explorer will not delete the corrupted directories. Like regular Windows the stupid thing hugs and protects corrupted folders and files instead of offering to get rid of them. If there was a program like Unlocker for WinCE they could be deleted.
