SOURCE: Touch screen not responsive

The cable to the touch sensitive part of the screen may have come loose (easily happens if knocked).

Try taking the unit apart (with care and the right type of screwdriver) and reseating the connector cable.

Once you've done this you may need to recalibrate the screen. Holding the power switch down will get you to the reboot / recalibrate screen.

But of course this will probably invalidate your warranty so beware.

Try performing a soft reset or a hard reset to the unit.
The soft reset is done by holding down the power button for at least 10 seconds and allowing the unit to power back on.
A hard reset is done by pressing and holding the bottom right hand corner of the screen while the power is off and then pressing the power button on. A pop up will appear asking to confirm the reset.
The hard reset will erase the user data, so it is advisable to save the data if possible.
Installing and running the Garmin WebUpdater to load or reload the latest update will resolve most issues.
download the latest version of WebUpdater software

The touch screen may need recalibration.
This can be done by pressing and holding the top left corner of the screen will powering on the unit.
Keep pressing the top left corner of the screen until the calibration screen appears.
Use a stylus or the round back part of a pen to press the dots to calibrate.
Once the calibration is done the unit will continue to boot up showing the Garmin screen.

Touch screen does not work properly in my Montana. An iconic brand and opens another. How I can resolve this? is a problem of firmware or software? I have a friend with the same problem with his Montana.

In most cases I have found the touch screen to be the problem, it will cause all kinds of symptoms, intermittent operation, freeze, to no access. The only solution is change the touch screen, depending on price it may be worth the repair, check ebay out because you will find the best pricing there.

Garmin Nuvi 660 touch screen freezes up. Soft

I sat on the phone for 30 minutes waiting for Garmin support when my Nuvi suddenly had no touch screen response. They had me delete a file on the device (with it hooked to my computer) then reboot and it went thru a touch screen alignment and it worked.

Sadly, it has frozen again and I don't recall the file (it had been a GCD file in all caps, that is all I know and I don't see a file in all caps any more). I will be calling support tomorrow.

My take is that it *is* a firmware thing *and* there is some way to reset the firmware.
