Garmin gpsmap 162 turns on, works for about two minutes, then a thin black vertical line comes across screen and screen goes blank with the line remaining. I have to unplug and start over. Same things happens. Is it dead?

    I have a Garmin GPS Map 76S. It will boot up and find satelites and go to the map page. Then in about a minute or so, the screen blanks out with one thin black verticle line through the screen. It won't turn off and it won't change pages. The only way to turn it off is to remove a battery for a second. So, it is a pretty worthless unit at this point. Would apprecaite any fix or maybe I can send it back to Garmin.

    Thanks,

AS previously recommended, turn off the Waas then go to the garmin web site and download firmware version 3.70, this will update the unit to work with the changes which have been made to the WAAS satelites. Install the 3.70 into your unit then you can use WAAS again and should have no problems. It worked with mine

Possible Solution found on google....

My old Garmin 162 chartplotter was mounted on the binnacle guard and served me
well for many years. Lately, it started getting very slow to refresh screens.
At times, it would shut down with only a black vertical line on the screen. On
our last cruise, the screen froze at a very critical moment. Too old to
repair, I bought a new Garmin 440, which I am very disappointed with, but
that's another story.
I read an article in the GoodOldBoat newsletter about the Department of Defense
making changes to the WAAS satellites that have caused problems in Garmin 72
and 76. Garmin's tech support recommended to turn the WAAS function off on
affected units. So I got out my old 162 and turned the WAAS off and it works
fine. To make sure it wasn't a fluke, I turned it off and on several times,
and it always slowed down with WAAS turned on. With it turned off, the
position error or accuracy, increases 1-2ft, not a big deal. I hooked the unit
up on my truck and drove around. Not a problem. Further reading indicates
that other brands of GPS are also having problems with the new WAAS
transmissions.
So if you are having problems with your GPS and it is new enough to have WAAS,
try to turn it off

Screen goes blank except for a verticle streak


I had the same problem (blank screen, vertical line). After speaking with Garmin, I was told to make sure I was using the latest software version, and to turn off the WAAS function. Disable it for now, because the WAAS signal, coming from the satellite, has changed, and Garmin has not yet published a remedy to correct this problem. A fix should be out in a software update, sometime in the future, hopefully. I also did the software update, to the latest version 4.0. The unit performs perfectly now, however, the accuracy is not quite as good, due to the lack of WAAS. Good Luck!!

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 locks up once satellite acquisition is complete.


Does the screen go blank with a faint vertical line (top to bottom)? If so, I had the same problem (blank screen, vertical line). After speaking with Garmin, I was told to make sure I was using the latest software version, and to turn off the WAAS function. Disable it for now, because the WAAS signal, coming from the satellite, has changed, and Garmin has not yet published a remedy to correct this problem. A fix should be out in a software update, sometime in the future, hopefully. I also did the software update, to the latest version 4.0. The unit performs perfectly now, however, the accuracy is not quite as good, due to the lack of WAAS. Good Luck!!

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.

Unit shut down


I have run into the same problem and it may be related to the WAAS (Wide Area Augmentation System) feature. Try disabling this feature (under MAIN MENU / Setup). I used this receiver overseas (Asia and Europe) last year for 35 days straight with no problems. During this time WAAS was disabled as none of these satellites are visible overseas. The problem occurred intermittently prior to the overseas trip, and has reoccurred after returning. I was running into the same problem this past weekend and noticed the screen blanking out (with the vertical line) shortly after differential corrections were applied to the GPS signals. I disabled the WAAS and let the receiver run for over an hour. The problem did not return. Hope this helps.

Screen Blanks

I had the same problem with an etrex Vista. I spoke with Garmin, they said that a recently launched WAAS satellite is interferring with some models (he mentioned it is the models with a black and white screen). Garmin tech support said that they're working on a software patch but for the meantime switch WAAS off.

Call Garmin tech support with any questions or to find out about the software patch, 1-800-800-1020

GPS screen went blank


My problem exactly. Unit would start up, acquire satellites, then the screen would go blank with a single vertical line. Unit would not respond to buttons or even turn off. Unit works fine after I did the reset:

- w/unit OFF, press and hold QUIT+DOWN+MENU
- press and release the power button, release DOWN, keep holding QUIT+MENU for 5 seconds.
- unit prompts something like: "erase all data;" choose yes.
- you will lose waypoints, etc.

Go to the Garmin support area for details.
