Before GPS systems, such as the TomTom line of products, lost travellers had to consult a paper map or stop to ask for directions. TomTom GPS devices, though, give you turn-by-turn directions as you drive. Even if you make a wrong turn, the GPS gives you a new route, so you're never lost. Before using the TomTom, however, it needs to have a fully charged battery. There are two ways to charge the device, and the GPS itself lets you know when it has an adequate charge.
Plug a USB cable into the cable jack on the TomTom, then connect the cable to a computer. This charges the device. Alternatively, it's also possible to charge the TomTom in a vehicle using a car charger.
Connect the TomTom to the GPS dock in your car, if it isn't already connected, and turn it on.
Look at the small blue battery icon on the left side of the main screen. A solid blue battery means the device is fully charged. The solid blue colour decreases as the battery charge gets lower. When the icon is just a blue outline of a battery, this means the battery is nearly empty. Charge the TomTom soon.
If you have a car charger, you can use the TomTom while it is charging.
