You must see the dealer on this. Sorry no at home repair is possible

This is due to a miscalibration of the touchscreen. The touchscreen needs to be recalibrated. A procedure can be found here:

Run the touch screen calibration routine by pressing the Menu Button, choose Display (if you can) and press the Find button. Follow the on-screen instructions to calibrate.

See page 42 http://www8.garmin.com/manuals/StreetPilot2720GPS_OwnersManual.pdf

If you think the touch screen is not responding properly, press and hold the Power button until the
Calibration screen appears. Follow the on-screen instructions.

The touch screen on Garmin Nuvi 660 is not working at all. It turns on, but when I touch the screeen, nothing happens. Could it be the battery. It was low, so I charged it for 45minutes, then the gps screen dimmed and turned off after just 10-15 minutes of "messing with it"

I don't have a Nuvi 2xx with me at the moment but on a 3xx & 6xx series, press the wrench symbol and then the display icon and select recalibrate screen and go through the process and touch the dots as it tells you to do. This will recalibrate the touch screen.

Hi,
looks like your touch screen is faulty . it could just be dust / dirt under the edges of the screen. If dust is trapped under the edge , it can effectivly be pressing the screen a little causing letetr to change or dissapear. See if you can get to clean under and around the edges , if the cleanup doesn't work then most likely cause is a faulty touch screen which will need replacing. Good luck.

Press the wrench symbol, choose 'display' and recalibrate...

You need to calibrate the touch screen. With the unit off press and hold the power button until the calibration screen appears (approx 35 seconds). The follow the instruction on touching the dot on the screen. Once this is done your screen should be OK.
