How does navigation work?

In order to navigate you to your destination, your TomTom NAVIGATOR must 

know where you are now. To find your current position, your 

TomTom NAVIGATOR uses the Global Positioning System (GPS). GPS is available 

for free and without subscription.

The GPS uses satellites to transmit signals to GPS receivers. Using the GPS signal, 

your TomTom NAVIGATOR can work out where you are and how fast you are 

going. GPS signals work in all weather, anywhere in the world.

Once your NAVIGATOR 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.
