Garmin 2595 Touchscreen does not work properly, it's shutting down by itself. I made calibrate, reset, and touchscreen diagnose, nothing helps

Sounds like it is running on low battery which tells me that it's not getting power, test something else in the cigarette lighter to make sure it is working, is there a fuse inside the cigarette lighter connection? if thats ok then check the condition of the cable connection in the unit. hope I helped you.

Please be more specific. There is a calibration screen where black dots are shown and you press them to calibrate the touchscreen. Is this what you mean? If you press them and nothing happens, your touchscreen may have failed and needs to be replaced.

You have not said what model garmin nuvi ?
The touchscreen on a Garmin nuvi GPS usually loses sensitivity or stops responding if it's lost calibration.
This usually happens after prolonged usage.
Touchscreen problems are also caused by dirt, smudges and improper care.
If your Garmin nuvi's screen isn't performing as expected, Garmin provides solutions and tips to not only improve the device's performance, but prevent premature wear and tear.
Calibrating the Screen

If the Garmin nuvi's touchscreen isn't working, you need to calibrate the screen.
Calibration resets and repositions the screen for optimal performance without deleting saved settings.
Before calibrating the screen, press and hold the "Power" button to turn off the device.
Pressing and holding the "Power" button again for about 30 seconds automatically displays the calibration screen.
Pressing the dot on the white screen calibrates the touchscreen automatically.

Updating Software.
If The Garmin nuvi's touchscreen is still unresponsive, updating the device's firmware to the latest version can solve operating system problems that lead to touchscreen problems.
Before updating the device's firmware, connect the GPS to the computer using the USB cable. When the computer detects the GPS, the "AutoPlay" menu appears on the screen.
Tapping the arrow on the menu automatically opens the "myGarmin Agent" download page.
From there, follow the prompts to update your Garmin nuvi's software quickly and safely.


Cleaning. In some cases, the Garmin nuvi's touchscreen won't respond to touch if the screen is dirty. Touchscreens are sensitive to dirt and smudges that decrease sensitivity.
If the screen is dirty, cleaning it with a soft, clean, lint-free cloth improves performance.
If the screen is severely dirty, using water, isopropyl alcohol or eyeglass cleaner removes tough stains.
To avoid damaging the screen, apply liquid to a cloth instead of directly to the touchscreen before cleaning it.

Tips.

Refer to your Garmin nuvi's maintenance and storage information found on the device's manual prevents premature wear and tear.
If the screen stopped working after prolonged exposure to extreme temperatures or water, the device's hardware is most likely damaged.
In such a case, you need to contact Garmin for additional troubleshooting and possible repairs.
Attempting to disassemble and repair the GPS yourself only increases the risk of damaging the unit even further.
also it could be a battery problem if the nuvi is not getting power ?

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.

My touchscreen on Garmin nuvi 1390 not working too and .calibration it's help alsoI did twice hard reset my GPS Garmin Nuvi 1390 and nothing happening and after I tried different trick,when I turned GPS off I hold the top left corner screen.The screen exchange for calibrations and I pressed several times according request and my GPS Garmin Nuvi 1390 started work,but repairing company wanna charge me $100 Canadian dollars.I didn't connect GPS to computer

Sounds like the calibration for the touchscreen needs to be reset. If you check in the control panel, there should be a ELO shortcut that allows you to calibrate/test the touchscreen. Try running through the calibration and see if the touchscreen behavior improves. If the calibration doesn't fix it, then you may have an issue with the touchscreen itself.

This is a common problem due to certain style of touchscreen that is known to fail due to temperature. if you can not recalibrate the screen, then the touchscreen needs to be replaced. More information, including the recalibration procedure can be found here:
