How do I activate my Audi navigation system?

I recently purchased an Audi and I'm having trouble figuring out how to activate the navigation system. Can someone explain the steps to me?

In order to activate your Audi navigation system, you will need to go into the car settings and select the navigation option. You will then need to enter your activation code, which can be found in your owner's manual or by contacting your Audi dealer. Once the code is entered, your navigation system will be activated and ready to use!
