I presume that you never updated your prior Maps app to version 7. It generally sucks compared to the older version, and has quite the learning curve. But to get started, start Maps. Assuming you're looking at a map screen, there will be a search box at the top, and at the right of that there will be a curved arrow icon. Hit that and it will bring up the navigation functions.
There will be a lot to learn. One thing important is to get a wide area view that shows traffic, you need to hit the the bottom right of the screen (three bar icon) and hit route preview. (There's also a tap, hit, slide down short cut, but it's not easier than just going through the menu.) The route line will be blue rather than green, but if there is traffic it will show a different color.
I checked in maps and didnt notice that little icon. I wouldnt have found it. I seriously thought Nav was gone.
Oddly, the look of navigation is nothing new to me. Its looked like this for a while, however I did still have the blue navigation icon until this morning after I installed the 4.3 update.
I hope we get the shortcut back. If youre in a car, the less buttons you need to press the better.
