Looking At A Mazda CX-3 .... Do I Need The Navigation?

In my current car, a 1996 Jeep Cherokee, I have a Ram mount installed that allows me to see the navigation on my phone when I'm using it, and to use the dashcam app as well. I would mount the phone similarly in the CX-3.

I use the basic Google navigation in the phone a couple of times a month, and it works well for me, aside from it being difficult sometimes to answer an incoming call while the navi is on the screen..

I'm wondering what benefits ordering the navigation package on the CX-3 might be, if any?
