Above is your user manual..

Go to your safety preferences menu and you should be able to disable the lock. If that doesn't work text back your model number.
you can turn this off by going into your tom tom prefrences and under the saftey heading un click it other wise i would set it back to factory defaluts but ensure that you back up your tom tom first or u may lose ur maps. you can do that by going on to tom tom home which should be included in the box otherwise you can download it from tom toms website.
