A friend of mine recently bought a 20087 VW Touran with built-in Navigon navigation. Unfortunately, it is not working due to - my guess - a corrupt sd card. I tried to copy the contents to a new card but one file failed to copy: MobileNavigator.exe.

The device seems to be a GPStar424BT running Navigon 6 on WinCe 5 (see [Please Register or Login to download file] )

How do I get a good version of the executable? Anyone here willing to share it with me?
Note: I don't need maps since they should be on the device. Just the exe file should be fine.
