TomTom is a GPS navigation systems manufacturer, which offers solutions for automobiles, motorcycles, cell phones and PDAs. Like other technical gadgets, TomTom devices too are susceptible to malfunctions and stoppages. If your TomTom device fails to respond properly, you can perform a reboot to get it running once again.
Charge your device for two hours or more after it stops responding. In some devices, a charging light appears when the charger is plugged in.
Look for a tiny "Reset" button on your TomTom device. Use a needle or paper clip to press and hold the "Reset" button for 15 seconds. The "Reset" button is only present in some TomTom devices -- for instance, GO 910/710/510. If you do not find this button on your device, see the next step.
Press and hold the "Power" button on your TomTom until it reboots.
