Getting from one place to another in a foreign country, and even here in the USA can be a challenge. On our first trips we had THE MAP OF ITALY. It was a big as a kitchen table, and once unfolded, it never returned to the same size nor appearance.
I thought I had the answer when I purchased a TomTom GPS and it had all of western Europe on a built in hard drive. As we pulled out of the airport in Roma, I turned it on ready to set my destination and all I got was a satellite view of the world. It took a week before I found that I needed to go to settings and change the map. Those days are long gone and dedicated GPS or the APS for your phone are much easier to use.
I like the advance planning ability to set up a route before you leave for a trip.
Above are the screen shots from the TomTom western Europe APP. It shows the instructions as well as a map of the entire route. This come in handy, as on occasion turns come quickly and can be a sharp right or left.
On the way to Cortona ( Under the Tuscan Sun) we came upon a bunch of switchbacks. This is common with the hills in Italy. But when you get there it is always worth the trip.
