No, you will need to replace the LCD screen. Unfortunately, Garmin will charge you almost the price of a new unit for fixing it. You might be able to find a used unit on eBay that is dead but has a working display and swap the displays but it requires some electrical & mechanical knowledge.

If I can find a display, I can put it in for you for a reasonable price.

Please let me know if I can be of further assistance to you.

Good luck!

I have a Garmin Nuvi 255 GPS and the touch screen will not respond to touch, How do i fix?


Try recalibrating the screen with this procedure. If you can not calibrate the screen, then the touchscreen will need to be replaced.

Nuvi 2xx/2xxW Series: Turn the Nuvi off. Place your finger on the upper left-hand corner of the screen and then slide the on/off power switch to the left and hold until you see the calibration screen.

Garmin streetpilot c330 no sound Everything works but no sound. i tryed the volume on the right side but still no sound. what could be the probs? Guarantee expired. How much could it cost to fix? Thanks!


It's the volume pot having a broken solder connection. Disassemble & touch the connection w/a hot pencil iron, but you'll need to do this under a magnifying glass, because of the size of the contacts.

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.

Waking up your c330...

If you left your Garmin c330 on running the battery will have 1% life left. If you turn c330 back on again, it will flash screen for 3 seconds then die, even charging it at this point will not wake it back up. TO BRING IT BACK TO LIFE... plug in the power home or car into Garmin c330. There is a tab in the front Garmin gray frame of your screen. You must take like your fingernails and under the logo "GARMIN" pull the whole gray plastic frame off. Underneath the plastic frame to the right hand side. There is a "RESET" button. Make sure power is plugged in while hitting reset. Your battery should come back to life. Cheers

Garmin 2720 touchscreen won't work, must use remote control.


I'll start with a comment I made on another post:

The touch screen is made up of several layers. A thin plastic layer, a micro thin metal layer, microdots for insulators, another ultra thin metal layer, and a final plastic layer. All of these layers amount to the thickness of a sheet of paper. This whole stack is bonded to a thin sheet of glass and placed over the actual TFT display.

It's amazing that you can see through all these layers and only lose 20% of the light. What's not so amazing is that those thin metal layers are prone to damage. I've seen several with no apparent damage that didn't work, and several with visible scratches that worked fine.

I usually start by installing (or reinstalling) v7.2 firmware and then attempt to recalibrate the screen, sometimes that works. Next I would try re-seating the 4 conductor touch screen pigtail in it's ZIF socket nestled between the big white wires on the display assembly. The last resort is to buy a broken 2600 or 2700 series Garmin and salvage the touch screen. Actually the real last resort is to have Garmin fix it for a flat $250. Good luck.

Garmin c330 cracked screen


You can buy a new C330 now for $125 - $175. It would probably cost that much to repair the old one, I would replace it.

This doesn't fix Sitfar's problem, but for those how might find this helpful from Garmin's site: Question:  The touch screen is not responding correctly when I touch it. How can I recalibrate the screen?
Answer: To recalibrate the touch screen:
  1. Turn the unit off.
  2. With the unit off, touch and hold the Power button for 30 - 40 seconds.
  3. Follow the instructions on the screen.

Try turning the unit off, then turn in on while pressing your finger on the bottom right of the screen and holding it there for about 30 seconds. This should bring up the calibration screen, which will have you press dots to calibrate the touch screen. See if this helps.

Try to calibrate the touch screen. Push and hold the power button on until you see a white dot on the screen. This is the calibration mode. Touch the dot and another dot will apppear, now touch this dot again, keep doing this until the unit reboot.

If you touch the 1st dot and nothing happens then the digitizer on the LCD is dead. If the unit is still under warranty, get a RMA and return it to Garmin.

Touch screen won't calibrate on garmin 2720 gps


The touch screen is a 4 wire resistive type made up of several layers. A thin plastic layer, a micro thin metal layer, microdots for insulators, another ultra thin metal layer, and a final plastic layer. All of these layers amount to the thickness of a sheet of paper. This whole stack is bonded to a thin sheet of glass and placed over the actual TFT display.

It's amazing that you can see through all these layers and only lose 20% of the light. What's not so amazing is that those thin metal layers are prone to damage. I've seen several with no apparent damage that didn't work, and several with visible scratches or cuts that worked fine.

I usually start by installing (or reinstalling) v7.2 firmware and then attempt to recalibrate the screen, sometimes that works. Next I would try re-seating the 4 conductor touch screen pigtail in it's ZIF socket nestled between the big white wires on the display assembly. The last resort is to buy a broken 2600 or 2700 series Garmin and salvage the touch screen. You could send it to Garmin for a flat $250, but that makes no sense at all.

If you get another screen (Garmin won't sell you one), Here's how to replace it:
Remove the six screw holding the case together.
Split the cases and pull the patch antenna out of it's slot.
Remove the four silver screws holding the display assembly into the front bezel.
Unhook the small ribbon cable that goes to the infrared receiver under the red lens.
Pull the display assembly out of the front bezel. It won't come all the way out because of cables.
Use a razor to cut the plastic tape holding the touch screen bracket to the TFT display.
Unlatch the 4 conductor ribbon from the ZIF connector nestled between the 2 big white wires.
Use a penknife to unbend the metal tabs keeping the touch screen from coming loose. I usually just do the two by the IR receiver.

When you reassemble, don't get frustrated with the gaskets, they're tricky but it can be done. Tom
