How to fix the navigation system in my Audi A6?

My Audi A6's navigation system has been giving me some trouble lately. Sometimes it doesn't sync with my phone and other times it gives me wrong directions. How can I fix this problem?

First, make sure your phone's bluetooth is turned on and that it is connected to the car's system. If that doesn't solve the issue, try resetting the system by holding down the power button for 10 seconds. If the problem persists, it might be a software issue and you may need to bring your car to the dealership for them to update the system.
