DCR-HC40 LCD works, but Touchscreen doesn't. I was able to calibrate once -- but din't hold settings. I cannot calibrate.

Try recalibrating it using the following method:

Nuvi 11xx, 12xx, 13xx, 14xx, 24xx, 25xx Series: Turn off the Nuvi. Place your finger on the upper left-hand corner of the screen and then push down on the power button to turn the unit on. Release the power button when the Garmin logo appears. Continue to press on the upper left-hand corner of the screen until you see the calibration screen. Press all of the prompted dots.

Once completed the Nuvi will display Calibration Complete

This will recalibrate your touchscreen to the LCD display.

If this doesn't resolves your problem. then your touchscreen may be defective and may need to be replaced.

The touch screens in these can shift. Can you rotate the screen and get the screen to work? if so it's possible if your skilled to recenter the screen then resecure it. of course you might end up having to replace it. I have replaced more of them than recentering them . Larry's Electronics [email protected]

This fault is often caused by a failing flat cable that connects the LCD panel and the rest of the camera. In its early stages it is possible to get the buttons on the touch panel to work by carefuly changing the angle of the LCD panel while trying out the buttons until you get a position where they work.
When the flat cable gets worse , the picture on the LCD panel will start deteriorating and go off altogether.
At this stage you may consider having the flat cable replaced.
