How Does Navigation Work?

In order to navigate you to your destination, your TomTom ONE must know

where you are now. To find your current position, your TomTom ONE uses

the Global Positioning System (GPS). GPS is available for free and without

subscription.

GPS uses satellites to transmit signals to GPS receivers. Your TomTom ONE

has a built-in GPS receiver. Using the GPS signal, your TomTom ONE can

work out where you are and how fast you are going. GPS signals work in all

weather, anywhere in the world.

Note: Your TomTom ONE does not transmit your position, so others cannot

use it to track you while you are driving.

Maps

Once your ONE knows where you are and you have told it where you want to

go, it uses the digital map on the memory card or hard disk to work out the

best route to your destination.
