Using a TomTom in-car satellite navigation system can help take the stress out of driving by guiding you to your destination along the quickest route. Operating the system while you are driving might prove distracting, so the TomTom comes with an optional safety lock that disables the user input buttons on the device’s touchscreen while the car is moving. Once you stop the vehicle, the TomTom automatically enables the input buttons again so you can find a destination or set a new route. Remove the TomTom’s safety lock feature if one of your passengers wants to use the touchscreen while your car is moving.
Tap "Change Preferences" in the main menu on the TomTom's home screen.
Touch "Show All Menu Options" to reveal all the options in the preferences menu.
Go to the second preferences screen by tapping the right-facing arrow button in the bottom right-hand corner of the screen.
Tap "Safety Preferences" followed by "Safety Lock."
Touch "Turn Off Safety Lock" to disable this feature. Tap "Done" to exit the preferences menu.
