How do I use the Audi MMI Navigation System?

I recently purchased an Audi A7 and I'm having trouble figuring out how to use the MMI Navigation System. Can someone provide a step-by-step guide on how to use it?

To use the Audi MMI Navigation System, first ensure that the navigation system is turned on and the map is displayed. Next, press the 'Nav' button on the MMI control panel. This will bring up the options for inputting a destination or searching for points of interest. From there, you can use the MMI knob to select and confirm your desired destination. It's important to note that for safety reasons, it is recommended to set the destination before starting your journey.
