How to Restart the NAV system in 2015 CX-5

Recently my nav system has been freezing up and eventually shutting off completely while driving or typing in a destination. Is there any way to restart the navigation system in the 2015 CX-5 without restarting the car? I have tried everything that I can think of, but parking and restarting the car is the only thing that has worked, and it isn't always an option depending on the neighborhood that I'm in. The dealership confirmed that I do have the most recent TomTom update installed.

Here is a video that I made of what happens when it freezes. After a few minutes of this the screen switches to the audio menu and the navigation button is disabled.
