Turn the unit off. Press and hold down the power button and keep holding it. You will see the screen light up and it will say "pre-boot mode". Keep holding down the power key. It will then say "booting". Keep holding the power button down. You'll then come to the calibation screen. Select the dots and you'll be back in business.

To perform a Master Reset on the nuvi 2xx series device:
Note: A master reset
will erase all waypoints or favorites and will restore your unit to the default
factory settings. But who cares if you have problems, right?
The device will automatically reset. Follow the on screen prompts then place
your device in an area with a clear view of the sky until it acquires
satellites.
Your touchscreen should now be recalibrated.
If the screen is still not responding, then the unit will need to be replaced with a new unit at this time.
