I have had a similar problem with a Tomtom - at some stage the maps became corrupted. 
The solution with the Tomtom was to plug it in to the computer via usb cable and re-load the maps. I believe Garmin have similar computer software available, but you may be able to find more information and relevant updates on the Garmin page for your item:
hope this helps.

I am trying to factory reset my garmin Nuvi 50lm. It is powered off for certain, and used my finger, a pencil eraser to hold down the bottom right corner for several min, nothing happens.

If you've tried the normal reset (hold bottom right corner of the touch screen while powering on) and that has not worked, it is time to talk to Garmin.

Hopefully, your unit is still supported and they can repair it.

If your unit is out of warranty or no longer supported, the ultimate "hard-reset" is to open the unit and physically disconnect the battery lead from the circuit board. There are videos on You-Tube.

My Nuvi 1340 screen went bright white when turned on last week - no supported - now in the bin!

It turned on and said touch dot several times now the screen is off center

Turn off Garmin. Pres top left screen and hold. While holding, turn unit on but keep holding corner. Once the black dot shows up again, use the eraser part of a pencil to chase the dot. That would give exact measurements. Your fingers may be wet or too large and are offsetting the screen area readings. Good Luck

Two things :
1. First a hard reset. Turn the unit off andunplug it from a power source. Then press and hold the lower right hand corner of the screen. While hold you thumb or finger here turn on the unit until you get the prompt erase all user data, tap yes and allow the unit to restart. Next we need to update the firmware because alot of the original firmware was buggy were the units would freeze up.

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

I have a garmin nuvi 660 it says "the screen is currently locked. press the power key to unlock." I have done this several times and even loaded up the latest software. I still get this message. When...

The on / off switch on top has 3 positions, it locks all the way right, when the unit is on make sure you have it in the middle.

There are icons near power button that indicate right side lock.

Hello, my Garmin 670 froze up on me and the touch pad does not work. I reset the unit several times without luck!! Can you help? Thank You Frank

You might just need to recalibrate the screen. Start by getting to the SETTINGS > DISPLAY page. Select RECALIBRATE and follow the directions.

Now, if the screen doesn't respond at all, you'll probably have to arrange for service. Contact Garmin Support for additional help with your nuvi 670 below:

I hope this helps!

Garmin Nuvi 680 Touch Screen "touch" works intermittently

Recalibration has nothing to do with repairing this problem. If the touchscreen is non-responsive, how are you going to recalibrate it when it doesn't recognize the key presses?

The problem is caused by a defective touchscreen. SHARP substitued a different touchscreen into the 6xx series that fails even when the glass isn't damaged. The problem is caused by a defect in the manufacturing process where the touchscreen connections becomes detached from the tail that plugs into the board.

The touchscreen connections between the screen and the tail are made from conductive ink that can fracture, most likely caused when pressing on the screen over time.

These defective screens can be identified by a white tail cap at the end of the tail, whereas the original touchscreens have a maroon tail cap. The original touchscreens will only fail if the glass has been broken.

I only use the original touchscreens for all of my repairs.

Garmin Zumo 550 Freezes

If the unit freezes with something on the screen, then the book that came with the unit tells you to push the power button and the + sign button at the same time and this should fix the problem. Good Luck.

Try to power up my GPS 60csx and the screen stays on for several seconds then fades out.

I would suggest that you try the following master reset and software
Please be aware that if you have not used your gps for a while it will
take time to download fresh information.
With the unit switched off please press and hold QUIT + MENU + ZOOM OUT
You will lose any data stored on the unit so back your unit up first. I
would also suggest running the latest software update from the following
link, if you have not already done so

Once all this is done please leave your unit with a clear view of the
sky and allow it to acquire a satellite fix. This may take time so
please be patient. Once you have a fix leave the unit for a further 40
minute to achieve a good almanac update.
