Help - my screen has frozen - I touch it and nothing happens

Help - I tapped Navigation but nothing happened - my GPS didn't open

Firstly - don't panic - it's easily fixed. It happens occassionally with every touch screen - PDA, GPS, etc - it just means the screen is gotten factionally out of alignment with the 'smarts' underneath.

To fix it

1. click on System in the main menu

2. On the next screen, click on Sys Info.

3. In the System Info screen, click on Calibration

4. Use your stylus to press down on the +  showing in the centre of the screen - it will jump to a corner. Keep pressing the  +  as it moves around the screen until you see the message 'tap the screen'. Do so - and your screen is calibrated again.

5. Close System Info  then System - and you're back to the Main Menu and ready to proceed as normal.
