Screen calibration

does anybody know how to re-calibrate the screen ?
it is becoming very difficult to select "1" or "Q" on the left hand side of my screen when entering a postcode ~ it tends to select 2 or W.
there does not seem to be anything in the "Change Preferences" menus....
TIA,
Rob

There is no calibration option in the menu.

Have you tried resetting the unit and checking there's nothing at the edges of the bezel causing a screen press?

I'd give tomtom a call on 08451610009 if it persists. If you are still under warranty they will replace it.
