Hi,
You may have dust particles or similar trapped under the touch membrain. This would cause random selection and result in the problem your'e describing. It's often the case that small particles can be trapped just under the edges of the screen by getting under the screen surround( bezel ).
Another similar problem can also occur if the TomTom is left in a cold car overnight after a warm / hot day where moisture can form under the touch screen membrain. This moisture can move around making random inputs to the screen.
Hope this helps.
Good Luck
