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.
The 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.
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 to work out the best route to your
destination.
Note: Your TomTom ONE does not transmit your position, so others cannot
use it to track you while you are driving. You can however send your position
to TomTom Buddies. For more information, visit www.tomtom.com/plus
