Question about Garmin GPSMAP 276C GPS Receiver

1 Answer

276C not locating any sats

My 4+ year old Garmin will not find a single sat. This has never happened. Nothing shows up in the sat bar window. I have tried:
1. Removed batt, press buttons, wait, reinstall batt and hit pwr button
2. Pressed Quit & pwr buttons together to pwr up
3. Swivled the antenna back and forth and then hit pwr button
It says it is acquiring but there is nothing showing in the window.

    Thanks for the reply. If the info below does not fix it totally I will give your idea a go.
    I might have stumbled on the problem. On an aviation site a guy told someone to hold down Out then press the start button. Don't release Out until the Accept screen comes up. That got it finding sats. I also learned I need to chg the internal battery. They recommended charging overnight. I'm doing that now and will test in the morning.

Going to give you a possible solution but i don't think you are going to like it. The problem sounds easy and being as the unit is way off warranty you may or may not want to try this. Sounds like what you have is a broken wire in the antenna or a bad connection, you might MIGHT be able to fix this by opening up the antennae portion of the unit and see what you can see, broken wire or bad connection will have that result. Cleaning of the connector or re soldering of the wire should/might fix the problem. Hope this helps

How do i unlock my garmin nuvi 310 deluxe


If you have a PIN number on your device you will have been asked to set a security location. When you are at your security location or within approximately 50 metres of your security location the device will unlock without the PIN number.

I'm not sure if you are aware but there have been recent warnings that sat navs may start to fail and will stop working all together by 2010.

Are all sat-navs going to fail in 2010? Jump to Comments
sat_nav_fail.jpg?w=300&h=200 Sat-nav systems could become defunct next year, according to a report from the U.S. Government.
It reckons a lack of investment and development into the U.S. Air Force’s GPS (Global Positioning System) will cause the failure.
But the U.S. Air Force said sat-navs will carry on working as normal. So who’s right?

I’ve been meaning to buy a sat-nav for some time due to my girlfriend’s “interesting” map-reading skills.
There’s no doubt reading a map can be more rewarding, but the convenience of using a sat-nav is a welcome one.
But recent claims from the U.S. Government’s Accountability Office (GAO) concerned me slightly. It warned the 20-year-old Navstar GPS system is in urgent need of an upgrade.
The GAO criticised the U.S. Air Force Space Command for offering the service for free, and said the lack of investment meant both military and civilian systems could be affected.
Apparently the GPS system overran its budget by £562 million and the next satellite is due to go into orbit in August 2009 – almost two years behind schedule.
“It is uncertain whether the Air Force will be able to acquire new satellites in time to maintain current GPS service without interruption,” the GAO said.
But the U.S. Air Force Space Command left a comment on Twitter declaring there is nothing to worry about.
“Be assured, the issue is not whether GPS will stop working. There’s only a small risk we will not continue to exceed our performance standard.
“Since 1995, GPS has never failed to exceed performance standards,” the U.S. Air Force Space Command said.
Drivers across the world will be affected if sat-navs fail to operate in 2010.
If the satellites do go down, a new EU sat-nav system called ‘Galileo’ could be in big demand when it goes worldwide in 2013.
Until then, I’m going to put my faith in the U.S. Air Force and take the plunge with a sat-nav.

This does worry me, because I have had simliar problems with my work's sat nav, even on clear sunny days.

Gps 276C doesn't charge fully


Garmin has updates for this issue on the website but it doesn't fix all the units. Mine for example still does the whole "charge complete" thing when showing 1/2 a battery. The funny thing is I let it drain and the unit stays on for about 10 hours after it says the battery is dead. Garmin is working on a new fix and they said it should be up in about a week.
