Question about Garmin StreetPilot c340 GPS Receiver

4 Answers

Garmin is frozen on, and will not respond.

While traveling, my Garmin has frozen. It is still on, but will not allow me to turn it on or off. I tried unpluging it, and it stays on the same screen. It has not changed at all. It does not respond to any touch on the screen. It is just over a year old. I have never up dated any maps or anything. Please help.

    I was downloading an update.  As the unit we restarting after the download, the device became unreadable by Windows.  Now all that happens on the unit is the 'StreetPilot' start up screen comes up.  I tried resetting and powering down, but nothing.

Have you tried resetting the unit? Remove the faceplate and press the reset button on the right side of the unit. This may help.

My Garmin 255W froze up in the ON mode. Nothing moved and I could not turn it off. With nothing else to do I let the battery run down. When the screen went blank I plugged it into the car and turned it on and it came alive as if nothing had ever happened except it skipped the previous 200 miles. There was a low battery warning but that was to be expected.

I have a Garmin 1300 and it does not boot. I get a splash screen and everything freezes up. I have tried to reset it. I have tried to restart it with holding the button down. Etc, etc. I have tried to start it with a USB cable hooked to the computer. All the usual tries. Nothing works. Garmin's site does not talk about this problem. I wonder why? Maybe I am the only one having this problem or maybe not? What should I do?'

Call Garmin support as they can usually try to rebuild the Software that is frozen. figure on a 15-30 min call to them. Ask for the Software team that can remote into your computer and do this for you.

Garmin nuvi 1450 cannot turn off,is frozen. hav been traveling for 2 days so has been plugged in most of the time

Have you tried pressing and holding the power button for about 8 to 10 seconds? It should go on then off. Then wait a few seconds the turn it on normally. This usually resets the unit.
If this does not work try a hard reset.
Press and hold (and continue to hold) the bottom-right corner of the screen while powering the unit on.

Continue to hold the screen until the "Do you want to erase all user data?" prompt appears.

Press "yes" and the unit will reboot. This resets all your location settings and user preferences.

If possible after the hard reset, let the unit sit outdoors in the open for about 30 minutes or so to let the unit re-acquire the satellite data.

Once it gets going update your gps at the Garmin site.
Thanks for using FixYa

Touchscreen not responding.

There are three levels of fixes, please try them in order:
1. Reset the GPS using the Reset button, on the back, just under the Antenna Hinge. Resetting will turn off the GPS, and then turn it back on, if connected to power. Test, if fixed, great, otherwise, go to fix 2.
2. Turn the power off, then press and hold the powerbutton for up to 2 minutes. The GPS will turn on, and display a "PreBoot Mode" message. When that message disappears, and the screen calibration screen appears, follow the on-screen instructions, and you are fixed. If you still cannot use the touch screen, repeat fixes 1 and 2 several times, just to be sure., then go to fix 3
3. The touch-screen glass has probably broken or lost its connection with the GPX motherboard. You can order new touch screen glass on the web and install yourself, if you are techy in nature, otherwise do a search for "garmin nuvi 660 repair" and choose your service.

Look near the SN # and press the reset button.


with the garmin off, hold down the right bottom of the screen and turn the garmin on, it will then ask you if you want to perform a hard reset. Choose yes and that should fix your problem.

To unlock a “frozen unit,
1. power it off
2. Remove the face plate, Gently pry on the face plane. In the center top edge (under the Garmin logo) you’ll see a small notch.
3. on the right side of the unit, press the reset button.
4. replace the face plate
5. Power it back up.
The unit should restart normally.
