The problem seems to be the my drive services from the TomTom Go app wich needs a internet connection. When I dissable the service wich is mainly needed for updates, at this moment there seems no problems anymore with starting.
Above means that when you want to update or synchronize settings,options or other stuff you had to manually enabled my drive services to do that and after that disable again.
I keep you informed when things change, it would be great if this is the cure.
