TomTom GPS devices can suffer from firmware issues that cause the on-screen keyboard to stop responding to your touch, the screen to freeze, or the device does not find and display navigation instructions. If the firmware on your TomTom GPS stops operating correctly, you can install firmware and software updates for the device through TomTom HOME. Before updating the firmware, you should reset the device. Resetting the device may help to resolve any firmware errors. Writer Bio
