Question about Garmin GPSMAP 440 Chartplotter GPS with Ocean Shoreline Info

Open Question

Garmin GPSMAP 440 will not power up! Worked a month ago, haven't done anything with it and now it will not fire up. It took a few seconds to fire up before, holding the button in. I am not sure if this is normal. I checked the boats fuse with Digital multimeter and have power going out. At the GPS side, I found just one pin in the cord with power...

    I have a Garmin 178 and mine powered on 2 days ago and now it won't. The only thing I that I did different was buy a new data card and install it, but I switched the old with the new while the unit was turned off.
    I read that some people held the power button down for 20 and 35 seconds and their's worked after that.
    Did you ever find a solution to yours?

SOURCE: Garmin C530 need pin to unlock

Have you tried putting the unlock code in the main directory?  To do this open up notepad or some similar text program and copy the code from the yellow sheet onto the note pad and save it as GMAPPROM.UNL.  Then open "My Computer" and locate the Garmin removable device.  Open the "Garmin" folder and copy that file to it.  Safely remove it from your system and turn it on.

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…….

I haven't used my Garmin GPSMAP 292 for a couple


Have you tried pressing Page + Power at the same time while starting the 292?
Seems like there is a well Kinoen problem with the auto locate locking in wrong position and IF you reset the past position memory by pressing Page + Power while Power up should fix the problem.
You still need approx 20min location time but its better than 12-24h.

Will not power on


Did you use rechargeable batteries? The Garmin seems to be extremely picky about enough voltage. I had good rechargeables which I use in my foto flashlights, but they did not suffice for the Gamin. Simple non-rechargeable batteries ones solved my problem. Not good for the environment, but for my bearings...

Locks up after a few seconds/have to kill power to reset


This may help. Mine has the GPS antenna build into the bracket at the back. I removed the bracket and the unit did not go into the error screen and the sounder worked fine. The GPS would not locate but it has not antenna attached so DOH!! I have orderd a new antenna with the BNC connector and will post if that fixes the problem. At this point I'm guessing its a blow GPS antenna.

GPSmap 60Csx power up problems


I had the problem where I ended up disassembling the Garmin and adding a small piece of plastic to the on/off button. For some reason the push button on the top does not reach the one on the circuit board.
