Device does not start or stops responding to commands

If your device is not responding, first check that your device’s battery is charged. Your device will alert you when its battery’s charge is low and critically low. If your battery’s charge is depleted, your device will switch to sleep mode. If this doesn’t solve the problem, you can perform a restart. To do this, press and hold the On/Off button until you see the TomTom logo and hear the drum roll.
