No Google Navigation icon on 4.3 and up

Which is as it should really (just a shortcut icon removed), Navigation is still there inside the Google Maps app.

It functions in similar way, just that you have to click on the Navigation button on the search bar. Think it’s to simplify icons a bit since the Navigation button inside Google Maps gets you to the same place as the Navigation icon, you’re not missing any functionality . Encircled in red below.
