Garmin 2720 lost sound

My Garmin 2720 has lost all sound - not even a click when I use the touch screen. I reinstalled the latest firmware but that didn't help. Till yesterday it would somtimes start speaking if I shook it around. I suspect hardware failure in the speaker but have no idea how to get the part and install it.

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.

Click on tool icon on lower right corner. Touch Map icon. Touch
map Info icon in center of screen. Touch City Navigator North America NT v8 icon so that the box is checked. Then click on back until you reach "Where To?" screen. If "Touch City Nav..." box is not checked, then you cannot input state.

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 2720 lost sound


It sounds like the audio power amplifier is failing in the unit, it's kinda classic for an audio amplifier to fail when it gets hot, then work again when it cools down.

I'd suggest deleting the language you're using, then reload v7.2 firmware and the language. No reason why this should work, but it doesn't cost anything. If not you're looking at a $250 Garmin flat rate repair.

Unfortunately, Fixya is not associated with Garmin. We can only answer device questions and can't speak for the company.

Unfortunately, the unit cannot be upgraded. Garmin provides both in and out of warranty repair service if the unit is having a problem. The 2720 sells for $49 on Amazon, so it probably is not worth your while to have fixed.

The 2720 is known to have issues unfortunately, it is pretty lowly rated on Amazon.

Gps 2720


I tried another power cord and that was not the problem. I did do a firmwre update and that corrected the unit. It has been working well for the past 3 weeks. You should go to the Garmin website and download the latest FIRMWARE update.

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
