Becker Z101 is a device that is originally running Navigon.

There is a simple way to run Primo (or iGO) software - but loose Navigon !

Delete the contents of the folder called "MNAV"
Copy the Primo software in that folder.
Rename Primo.exe or iGO.exe or MobileNavigator.exe to Shell.exe


I did not test this - You do this at your own risk !!!
