Anyone know how to override the nav system on a 2013 prius persona

There is no menu button, so the old means don't seem to work. Any idea how to get to the nav override statement menu?

Thanks a ton!

What I really want is to just disable the nav/phone menu "grey out" when driving. I always wear my seat belt, but I'd like to turn off that infernal beeping when I put my laptop or dog there as well.
