Turn on the system by sliding
the switch on the top to the left. Wait for the system to load and click
"Agree" when the warning message appears (Never use the Garmin Nuvi
while you are driving).
Press "View Map" on the menu
screen, and wait for the device to acquire the satellites to determine
your current location. This could take up to a few minutes, depending on
your location. If you get a message saying the device could not find
the satellites, try moving outdoors or into a more open area.
When the device has connected to a satellite,
simply press on the blue arrow marking your current location. Note: the
blue arrow is the default setting; if you have changed your vehicle,
press on whatever you have set as your vehicle marker.
A screen will popup
that shows your current coordinates and asks, "Do you want to save this
location as a Favorite?" Click "Yes," and then enter whatever you want
to name the location.
Press "Menu," then "Where to?"
and then select "Favorites." Here you will see the location you just
entered and you can now navigate to and from this spot quickly and
Press and hold the antenna signal strength icon on the display to bring up Satellite reception information. This will show you what, if any, satellites are being tracked. It will also tell you if you're in DEMO mode, in which case real satellite signals won't be used for the position.
Additionally, you can check the hardware by using the built-in hardware self-test features by pressing and holding the battery icon. Examine the information presented on multiple pages by pressing 'next'. Look for the hardware TEST button and press it. Wait several seconds for results.
These two steps should at least tell you where the problem is. If you ARE getting Satellite signals but they aren't being used by the hardware, you may need to reset your unit. Also check for firmware updates by using the Garmin Update utility available on their web site.
I just went through this with Lowrance. tthe LGC 2000 module on my LCX 20 depth finder "quit responding" out of the clear blue. You have to go Lowrance.com and they have some tests you can follow to see if it is a bad cable or the module itself. I had to replace the module. They charged $99 bucks plus $12.50 shipping for a new one. I bought it spring of 2008, and the unit was 3 months out of warranty when it quit working. Last season I had lower back fusion and didn't use it except for 2 times late in the season. Getting ahold of Lowrance is going to be an experience. I called twice and waited on hold over 35 minutes before I was suddenly cut off both times. I tried email too, but it took 3-5 days to receive a response. Mine broke down June 18 of this year. I started trying to get hold of Lowrance the next day. By the time all the back and forth emails with the delayed responses were done, I received my new unit on July 24. 5 weeks! with out my gps in MN. It is a short season up here as it is. I sure didn't enjoy waiting that long.
Do the following:1 - Make sure you have fresh batteries in the unit and turn the unit on.2 - Check the GPS date and Time. On the Main Menu at the bottom of the screen, you can see a date and time. If the date and time are not current, then the clock is your problem. You will have to wait for the almanac information to be updated. Details are below in a later section.3 - Make sure your GPS is in the Normal Mode and not a demo mode. Verify other systems settings.
Go to the main menu and click on Setup icon.
From the Setup screen, access the System screen icon.Verify the following settings: GPS: normalWAAS: EnabledLanguage: English or your choice.Battery: Set according to your battery types.4 - Check your GPSs Version Software.
Go to the main menu and click on Setup icon.
From the Setup screen, access the System screen icon.
From the System screen, access the sub-menu icon in the upper right bar.
Select "Software Version" from the list. Verify the actual software version for me.The latest version available for the eTrex Legend is version 3.90 dated March 2008.http://www8.garmin.com/support/download_details.jsp?id=711Update the unit using this latest software and using Garmin's Webupdater.http://www8.garmin.com/products/webupdater/howtoinstall.jspIf that won't work, use the following download page to access the latest software updates per units.http://www8.garmin.com/support/blosp.jsp5 - Resetting your GPS clock and almanac informationNext you may need to acclimate your unit to a new date and time (almanac information). If you had your unit off and without batteries for over a month since you last accessed satellites, then your clock and almanac information may be incorrect. Even Garmin acknowledges this problem after software updates and the problem with accessing satellites. They state: "unit data including alamanac information may be incorrect or cleared. Back up all user data before upgrading. After installation is complete, place unit with a clear view of the sky for 15-30 minutes to re-acquire almanac data. "I know of no way to reset the clock using the GPS menus. All I can suggest is that you do the following:A - turn the unit on and wait 5 minutes or so for the "Poor Satellite Reception" screen to appear. See page 7 of the owner's manual.B - Set the "new location" to your area using the map when the "poor satellite reception screen" appears. Be sure to use the "map" option and not the "automatic". C - Set the GPS outside with a clear view of the sky. Check on it every 10 minutes. When the "Poor Satellite Reception" screen appears again, then click on "Restart Search". The "Restart Search" option is used when the date provided in the GPS is not today's date. (See page 7 of the Owner's manual for an example)Legend Owners Manual: http://www8.garmin.com/manuals/eTrexLegend_OwnersManual.pdfD - Once the GPS can track 4 satellites, then the clock should reset and you should be fine. This process could take up to an hour. I have had this problem with my eTrex Vista and eTrex Legend (both backup GPSs) and resolved it by having the clock reset. In fact, I just tried my eTrex Legend today after not using it for many months and storing it without batteries and it had this same problem. I followed the steps above to fix the problem. This took about 35 minutes.
