Question about Garmin GPS Devices

1 Answer

I have a garmin GPS map 162 and during operation the screen goes blank except for a vertical line.None of the controls allow me to shut down, I must disconnect the power. I called Garmin and they sent a note recommending that I upgrade my software but I can't find a place while operating with a direct 120 transformer where the information regarding what system I have is located. I don't know if it's a hardware or a software problem

    I'm beginning to wonder if this isn't some type of power fluctuation on my boat. Same description as yours... but I bring the unit into the house and it stays on with no issue... however the weather might be a factor... regardless.. I took a voltmeter to my power supply on the boat and did not see any power flux over a several minute period.. regardless, more isolation is needed before I can say where the problem really is...

The problem is the government made changes to the WAAS satelites. When the GPS tries to find the sattelites, it can't lock on and goes into an error mode and locks up.To eliminate the problem disable the WAAS which can be done when starting the unit. Then go online and download the 3.70 firmware version and load it into your unit. This will correct the system to function with the newer WAAS system. After installing the 3.70 software then you can enable the WAAS function.
Good Luck

Etrex Legend locks up, screen blank except vertical line


Is the unit being bumped during use? If not, sounds like a call to Garmin tech support is in the works. My thought is that it's something defective inside your unit.

Screen goes blank after locating sattilites.


Accordingto Garmin, this problem can be fixed by disabling the WAAS feature in teh set up menu. There is an incompatibility between the old Garmin software and latest WAAS upgrades. Later software from Garmin is supposed to fix this problem.

GPSr shuts off


Firmware needs to be upgraded on these units because the atellites are changing every so often so does the programming in these units, check to see if there is a firmware upgrade to fix these problems, the line in the middle of the screen is because it either hung during the process or the units lcd is going bad.

Just quits


I had the same problem (blank screen, vertical line). Per Garmin, turn off the WAAS function. Disable it for now, because the government has changed the WAAS signal coming from the satillite, and Garmin has not yet come out with a remedy to correct this problem yet. It should be out in a software update sometime in the future...............I did this and it corrected my problem immediately. The unit performs perfectly now, however, the accuracy is not as good, due to the lack of WAAS.......................

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 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...


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

MAP 76 locks up in normal mode after acquiring and starting to track, three to four minutes. Screen goes blank except for vertical stripe, no keys work. Have to pull batteries to turn off. Unit works...

What you said does make sense. When you have your unit in simulator mode, the GPS receiver is turned off, so it is not receiving signals from the satellites. The strange signal from the WAAS satellite must be what has been messing things up. Good Luck!

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.

Navigation screen freezes GPS unit


I believe they fixed this problem with a firmware upgrade. Use Garmin's web updater to perform the updates.
