I had the same problem? GPSmap76S was hung up trying to AutoLocate. It just couldn’t find itself, and it just stopped working all of a sudden one day, while I was traveling. I spoke with Garmin about the problem, and they advised me of an ongoing problem with WAAS. I was told that I should "Disable" WAAS, because the signal from the WAAS satellites had been changed by the government, and Garmin had not yet put out a software update to address the problem, on the 76 units, anyway. Also said that an update "should" come out, in the future, however, no commitment or promise on that. Evidently, once your unit hits one of the WAAS signals, it scrambles up the receiver in the GPS, because mine sure went crazy. The support guy also said, that if this did not correct the problem, I might also want to try a "Master Reset". So here’s what happened.
I disabled WAAS, but this did not correct the problem. The unit was still lost out there somewhere, trying to AutoLocate, so I ended up doing the “Master Reset”. Please read up on this procedure before trying it, and understand that you “will loose” any settings that you might have made to the GPS, along with all waypoints, routes, tracks, etc., however, my maps actually remained in tact? This procedure will actually set the unit back, just as it was when it originally came from the factory. Once completed, you will then have to allow the unit to initialize it's self again, just as you did when the unit was new. If you have forgotten about doing that, it simply means that you need to set the unit outdoors and leave it “on” for a while (15 – 20 minutes), until it actually AutoLocates it’s self, or locks in on your current position. Once this is done, re-do your setting preferences, back to the way you had them before the Master Reset. At the very least, you’ll have to re-set it to the correct time zone, and tell it about daylight savings time. Note: It’s a very good idea to go thru first, and jot down your page settings and main menu settings, before doing this procedure, or the screens may not look familiar to you, once the unit resets. You think you’ll remember them all, but you won’t. But whatever, once you have done the “Reset” and “Initialization”, you must now hook the GPS up to the computer and reload your waypoints, routes, etc, back to the GPS. You did have them saved on your computer, didn’t you? Hope so… If so, you should now be good to go…………….
My unit now works like a champ, good as new, just not as accurate, due to WAAS being turned off. I still don't know if the WAAS issue, was part of the problem or not, but I do know that the Master Reset got the unit back to working immediately, allowing it to locate itself almost instantly. What a relief…………..it’s a little work, but it takes much less time than it took you to read this post…………..
Hey, when all else fails, call Garmin 1-800-800-1020. They are good guys and willing to help, in fact, I would advise you to call them before you do anything, so you can describe to them, exactly what your unit is doing. I am only relating my situation and what happened to me. Your situation may be different……. .

I have a Garmin 76. One day the thing wouldn't pick up satellites at all. I tried the obvious things with no luck. I emailed Garmin for help and they suggested:

'Performing an auto locate on the unit to correct this issue. From the main menu page, select satellite, then press menu and select use with gps off, then press menu, then select new location, select automatic. I would then suggest taking the unit outside and letting it sit stationary for 25 minutes to re acquire the necessary satellite almanac data.'

This worked. Hopefully this solution will work for some other people. Sudden lack of ability to gain reception seems to be a common issue - I guess there may be different causes.

When I have seen this problem in the past it generally means it is time for a new unit or a repair. It is a hardware issue that a user can not fix. For your local repair depot please contact Garmin @ 1-800-800-1020

Garmin GPSMAP 172C - cannot find satellites (WAAS)?


WAAS is a seperate service from GPS. It provides GPS corrections so if you can not get WAAS there is no big problems. you unit just wont be as accurate as normal. WAAS only is for North America and EGNOS for Europe. You may want to turn WAAS off for now. I suggest trying a update for the unit. You will need a memory card and Garmin USB programmer. Then just go to garmins site to get the latest update. If you need a USB programmer feel free to Contact GPSCity.ca or GPSCity.com. They are the leading experts in Garmin GPS.

My device has seemed to have lost its ability to acquire satellites. Any suggestions? It's Garmin GPSmap 60CSx. Thanks.


I would try a reset and firmware update first. To Reset the unit hold the Page and Enter keys down while you power up the unit. hold them down until you get a prompt asking you if you really want to reset.

Garmin has a free software called webupdater. this will put the latest software in your unit. If there is a GPS chipset software available please apply that also. It will be in the list when you run webupdater.

You may want to try an external antenna also to see if an internal connection came loose.

GPSmap 296 doesn't show any satellite signal


Check that the date shown on the unit is correct. If not, choose autolocate and allow about 10 minutes for the unit to find satellites. If this works, then the internal lithium ion battery is defective.

Hooked up this spring but can't find satellites. Nothing has changed


Thanks for the comeback.

Problem was my antenna wire. Somehow the wire wore through where it went through the hard top. Probably due the the high winds we had this winter which caused the cover to rub and pull against it.

Thank you

Blank Screen on Garmin E-Trex Vista


The problem is that your software version needs updating. A recently added satellite creates a glitch in the older software. Go to the Garmin website, load WebUpdater if you haven't already done so, and the updated version (3.8) will automatically install to your Garmin unit. I had the same symptoms, they have now disappeared and my Etrex Vista is back to normal.

Garmin GPSmap 76 not acquiring satellites


You need to do an auto locate. This also corrects your time issues (wrong date and/or time will be corrected. To do an auto locate do the following.
  1. Start with the unit turned off.
  2. If you have a GPSMAP 76, GPSMAP 76C, or GPSMAP 76S, hold down the Page button. If you have a GPSMAP 76CSx or GPSMAP 76Cx, hold down the Zoom Out button.
  3. While holding down the first button (Page or Zoom Out), press and hold the Power button.
  4. Continue to hold the two buttons until the Satellite page displays. You can then then let go of the buttons.
  5. Finally, let the unit sit outside with a clear view of the sky. Allow about 20-40 minutes for the unit to acquire satellites.
