How Does Navigation Work?
Global Positioning System (GPS)
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.
