Garmin StreetPilot 2720 GPS Receiver Questions & Answers
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

Garmin GPS 2720
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.

Take the GPS out of your van to an area with a clear view of the sky. Power the unit on. If the unit is working correctly, then it will acquire the satellites. You can then put the unit back in your van. You may have to reposition the unit to keep the satellite lock.
If the unit does not acquire satellites outside, then the unit is defective.

Unable to update unit
When you plug in the USB cable, if your System, Hardware, Device Manager lists "GARMIN Devices", then the problem has to be in your network connection or Garmin WebUpdater. If your Device Manager doesn't list "GARMIN Devices" then the problem is in the computer, USB cable, or 2720.
I have three 2720s right now with bad USB ports. I'm going to try replacing the USB driver chip in each unit, but now I'm just guessing. Hope this helps. Tom

My 2720 turns on fine
I will suggest you reset your GPS before trying to update it, to reset your gps, follow
this steps, turn off your device. Press down on bottom right corner of
touchscreen, and then power on the GPS unit. You should be prompted
whether do you really want to erase all user data, or asked if do you
really want to start up in maintenance mode. Press Yes to reset
(warning: all data will be erased and lost, so backup before proceeding)
or enter maintenance mode.
Once the GPS unit is reset, remember to place the device
outside where there is a clear unobstructed view of the sky for 15 to 30
minutes in order for it to requires fix to GPS satellites. After this, you can
now try again.

Touch screen will not calibrate
Welcome to Fixya. In order to calibrate the Garmin 2720 please follow the steps below.
1. Calibrate the screen of the Garmin 2720 to fix the touch screen when it will not recognize that you are pressing it. Press the "Menu" button of the remote. Select settings and then display from the remote. Hit the "Recalibrate" button and follow the instructions on the screen, which will tell you where to touch the screen for calibration.
2. Check that the batteries are in the remote correctly. Look in the battery compartment on the rear of the remote to check that the "+" and "-" on the remote and the batteries and align them if they are not correctly matched "+" to "+" and "-" to "-" polarity. Point the front of the remote at the IR port on the front of the Garmin 2720 and press any button to see if the remote is working. If not, get new batteries.
3. Replace the two AAA batteries in the remote. Put the new batteries firmly into the battery compartment with the + and - polarities of the batteries lined up with the appropriate polarities in the remote. Put the back on the remote and test it by pointing it at the IR port and pushing a button.
4. Reset the Garmin 2720 to the original settings to clear data. Press the power switch on the right side of the unit if the looking at the screen to turn the unit off. Press the power switch again to turn the Garmin 2720 on again. Press down and hold the "Find" key on the front of the Garmin 2720, which is the button near the top right corner of the screen. Hold the button down until you see the message on the screen that reads "Do you really want to erase all user data?" Select "Yes." Be aware that doing so will delete all of your data, including your recent finds.
5. Load the USB drivers to fix connection problems with your computer. Insert the USB driver CD-Rom into the drive on your computer. Select "Start" and Run" if the software does not load by itself. Type the letter of your computer's CD-Rom drive and then type "setup." Press the "Enter" key. Your computer will walk you through the rest of the installation process of the USB drivers. This will be different for each computer depending on your operating system.
6. Connect the power cable of the Garmin 2720. Plug the mini-USB connector into the connector on the back of your Garmin. The connector is located underneath the weather cap, which is toward the bottom on the left side of the back of the unit. Access the connector by lifting the weather cap flap. Insert the available end of the cable into a USB connector on your computer.
7. Call Product Support in the U.S. at 800-800-1020 if you have any other issues you cannot fix by following these directions. Call 44-0870-850-1241 if you are in Europe.

Garmin 2720 touchscreen won't work,
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.

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.
