Question about Garmin GPSMAP 76 GPS Receiver

3 Answers

GPS screen went blank

While moose hunting I had my GPS on for about 45 minutes and the screen went blank. I tried to turn it back on and nothing happened, I replaced the batteries with new Rayovac batteries and it turned on and went blank again in less than one minute. I replaced the batteries again with new Energiser batteries and it worked fine again with no more problems for the rest of the week long hunt. After returning home from the hunt I turned the GPS on in my yard and the "distance to the nearest waypoint" reading (home) kept jumping from 27 metres to 289 metres, the sceen shifted side to side a couple of times also. Are these problems related? Was the first problem battery related ? Was the problem at home satalite related? Thanks for the help, Hotch.

    I have a similar soon as my GPS starts getting sattelite reception the screen goes blank and has one line through it. If I hit the menu key before sat reception is acquired I can go into any of the gps functions but if I go back to the sat reception page the screen goes blank with a line through it and the only way to get rid of the line is to remove the batteries.

    I have experienced exactly the same problem described above. I get a single vertical line down an otherwise blank screen after the GPS successfully acquires satellites. I did indentify a contributing factor. My GPSMAP 76 is mounted in my boat with a factory mount and 12-volt wiring harness. I first hooked it up three months ago and have been using it all summer with no problems. Then the problem above occurred. I found that when I disconnected the power supply, pulled the AA batteries to clear the problem, then powered back up on the AA batteries, the problem did not return. The moment I tried the external power cable, the problem reoccurred. Could this be a power overload defense? I have not changed anything with the boat's electrical system. I saw the problem reappear once with the engine running and once with the engine off.

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.

It looks like a software upgrade did the trick in my case. I upgraded from OS 3.8 to 4.0 and the last time I had my boat out the GPSMAP 76 worked just fine.

Its normal for position to shift but not that much.  Try again and look at the sat status screen to see how many satelites you pick up and how strong signal is.

It's most likely that software failure caused GPS to chew up the batteries.  The GPS uses a lot energy while acquiring.

If your software is less than v4.00 then download this update:

GPSMAP 76 Ver. 4.00 as of Nov 29, 2006

If that doesn't work it may be necessary to do a master reset.

Display went blank to the calibration screen while traveling

Try using a stylus if you have one or a pen (tip retracted) on the screen. Meaning something finer and thinner then your finger. Don't know why but this works on my unit when the recaibration screen comes up.

Turn it on screen went blank will not come back on

Hello there:
First if this unit has a restet button it hold it in for 3 minutes and than try it if still nothing, the device has a fuse that is located on the inside of the unit that probablly has failed and needs to be replaced also you may want to make sure that the battery terminals are not loose and are clean.
You can also take it to a authorised dealer to have it bench tested ok?
best regards michael

Garmin Nuvi won't turn on

See if you can find the reset button on the unit and push it while the unit is on. On newer units the reset button is on the back, but on older units it may have a faceplate cover around the edge of the screen you have to remove and the reset button is sometimes located under the faceplate...this may work
