If you are plain Zurich installed with its latest installer, to activate the Docking systems you need to use the ParkMe function, were you first select a parking, and it then activates the Docking system.
If, instead, you install GSX, which is entirely free to use at our sceneries without any limitations, the ParkMe system will be replaced by GSX, which is way more powerful, and still use a similar system, were you first select were you want to park, then the Docking (or a Marshaller, if the parking doesn't have a Docking system)
So, I strongly suggest installing GSX, and use that one.
