Question about GPS Devices

Open Question

When my Garmin 2720 is hooked up either to the car or in the house, it lights up comes on but cannot find a satellite.. this is on a sunny day. I've had it for 3 years same location and never had this problem. It also says in upper left corner GPS off?? Not sure what that means there is no setting to turn it off and on other than the on/off switch.

    My Forerunner says GPS off when I first put it in training mode. It does not search for Sats. I have reset it several times but It still does not try to aquire a GPS Signal.

    What should I do next?

SOURCE: Garmin Nuvi Firmaware Update Complete, Unable to catch satellite signal

So what happens when you connect it to the PC?
Make sure no sd cards are installed while you do this.
download and install web updater, run it it gets to a screen where it looks for the gps, plug the usb cable into the GPS (no USB hubs please!!!) Make sure it detects the GPS before you continue. Select the updates you need (don't install all the languages !!) after this is done the program will report the downloads are on the garmin, unplug the unit and it will reboot and whilst rebooting it will install the updates....so don't touch it until it reboots again and displays the regular screen....and make sure the batery is fully charged before you do this...!

SOURCE: 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

Sounds like you need to recalibrate the screen. This can be done by following the steps below:

To Calibrate the Touch Screen on a zūmo®:
1. Turn the unit Off and make sure it is not attached to any outside power source.
2. Power the unit On, continue to hold the Power button for 1 minute. 3. A screen will display that says, Press dot in the lower left corner. 4. Release the Power button and touch the sequence of dots until your unit says Calibration complete.

Good luck!

Hello,

Log into your account at www.garmin.com by using the myGarmin link.
With the unit connected to the computer go to the myDashboard link.

From there you should be able to apply the update.

Voice activation capabilities locked and none functioning after driving for 2 hours or so. Satellite reception getting lost even on a sunny day


I can help you reset and fix your Garmin Nuvi 265W.

Erratic behavior and improved satellite reception has been addressed in new system software / firmware update.

There are three steps to take to get your Nuvi 265W running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.

I hope that helps.

How does one update th gps?


You connect the 2720 to your pc with the supplied usb cable.
Power up the 2720 with the ac supply cable.
Then run the garmin webupdater. It will do the update.

You must have previously installed the webupdater and the usb drivers. If you use the garmin mapsource software and can connect to the 2720, to transfer waypoints, tracks, etc., then the usb drivers are already installed.

You can download the webupdater at this site:

Hope this helps.

Searching for satellite but never finds - what is wrong?


I had one like that last year, I found if I lied to it when it asked what state I was in, then it would find the satellites and work fine ... until the next time you turned it on. That one was fixed by installing new v7.2 firmware using Garmin WebUpdater through the USB port.

I've got one right now that won't find the satellites and the firmware trick didn't work. That's all I've got so far. Tom.

My Garmin has stopped finding destinations - just says "Searching for Satellite)+


I had the same problem with my Nuvi 310. Found a solution in here that works. Here's a copy of the advice.....note you will need to get in the car and set it for a destination and go. 5-10 mins later the Garmin Nuvi will lose the satellites, but don't adjust it it, leave it on and keep going. Eventually after about an hour it will right itself, pick up the satellites and evrything will be back to normal.

Here's the advice:

I experienced the same problem about acquiring satellite signal even when it's a clear sunny day. After 30 mintues, it was still searching!
The unit appeared to have "stuck" in this acquiring mode. The following worked for me:
1) open the GPS antenna
2) press the bottom left screen while holding the power button to turn the unit on
3) enter maintenace mode
4) select diagnostics
5) clear error report, do NOT clear any user data
6) restart unit the usual way

My GPS 350 was able to acquire satellite signal in less than 1 minute after the above steps were taken.
