SOURCE: Garmin GPSmap 76 not acquiring satellites

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…….

SOURCE: unable to acquire satellites with my garmin

I find my Garmin 305 is a slug to locate and lock on. But if I pull it off the charger just before I go for a run it locks on all most immediately. Give it a try and let me know if it works.

My Garmin 310 xt always worked prefectly. Suddenly this week it won't acquire satellites.


Hello,

Try giving your unit a firmware update using Garmins WebUpdater software, it can be obtained from this link http://www8.garmin.com/products/webupdater/howtoinstall.jsp. If this dosent work your units GPS receiver is probably dead and should be sent in for repair.

Hope this helps!

GPS wont aquire a satellite


    Hello there and happy new year
    If Your Unit Cannot Acquire Satellite Signals
  1. For your Garmin GPS unit to acquire the satellite signals it needs to function properly, the unit must be taken outside, away from mountains, tall buildings and heavy foliage where it can get a clear view of the sky. Keep the unit stationary for several minutes while the GPS unit acquires the necessary satellite signals.It may take several minutes for the unit to locate a good solid signal
  2. OK
  3. Hope this is very helpful please keep me posted on this ok?
    Best regards Michael

GPS problems wit a Garmin Forerunner 405


The instructions say touch and hold GPS and to go outside away from tall buildings and to remain stationary for several minutes. Not really sure what their definition of several minutes is guess thats their way of saying "sit still for as long as it takes." If that doesnt work I would get in touch with Garmin. 1-800-800-1020
