When I programmed the FMS, is there a way to do a step-by-step walkthrough of the entered route, on the PFD?

Absolutely.

 

Below the FMS you'll see a button that says "Format". Press this once and it will change the nav display to a zoomed out format and allow you to step through it by clicking through each waypoint in the FPL pages of the FMS.

 

Just press the format button again to change it back to the standard nav display.

Just note that you can't scroll through every individual waypoint.

Thanks guys!
