Ever since moving my GPS unit form Idaho to California the coordinates seem to bee off by 20-50 feet. I have turned on and off the WAAS and it has made no difference. I had this problem two times in Idaho but have it all the time now. In Idaho it seemed to be fixed by shutting off the WAAS. I have reset and reloaded and updated all software. Any suggestions would be usefull.

Re: Coordintates seem to ALWAYS be off by 20-50 feet
How are you determining your error? If you are comparing your position to a map and you are getting error consistently, it could be that your map datum does not match the datum set in the GPS. Without WAAS turned on, your error should be @15'. With WAAS on it should be @ 6 to 9'. If you are using the Sattelite screen to determine your error, remember that is just estimated error. Higher estimated errors can be caused by satellites that are blocked or not visible to the GPS, or poor satellite geometry. It is normal for example, to have more error in high northern or southern latitudes due to less satellites being visible. With good reception you should be able to see 8 to 12 satellites on your satellite page. Signal strength is also important, You can have a lot of visible satellites but if the signal is weak your error wil increase. The signal can be weakened by heavy tree cover or high objects such as buildings or mountains. Such interference is called signal path error. Another form of signal path error is when the signal gets reflected off something before it gets to your GPS. For example; you're in a canyon and satellite 1 is to the east of you. The eastern rim of the canyon blocks the signal from satellite 1, however the signal bounces off the western rim and your GPS then picks it up. Because it took longer to get to your GPS, the GPS thinks that the satellite is farther away than it really is, causing a postion error. (This would not show up on your estimated position error shown on the satellite page because the GPS does not know this is happening.)
When WAAS is turned on it takes a channel that would normally be dedicated to a GPS satellite. It's possible that turning off WAAS helped you because having an extra GPS satellite improved your geometry which improved your accuracy more than the corrections WAAS is designed to make. The next time your error seems high, check how many satellites are being tracked and how strong the signal is.

You need an App that will give you your current GPS coordinates.
Install an App Like MotionX or similar. Check the Latitude & Longitude or Better still the UTM Easting & Northing (same thing but UTM is the new digital coordinates & is easier)
Compare one phone coordinates with the other phone.
they should be almost identical if your in same location.
Otherwise check your phone SETTINGS for GPS & how it's set up.
Even a standard Garmin GPS tracker (which I use for prospecting) can be set fro the wrong side of the world. Usually its set for WGS 84 or 94 & UTM. I have seen people set up for the northern hemisphere when they are in the southern hemisphere.
Also, you said that your husbands settings never change. Well... it's GPS either turned off or broken.
I also use my "Find My Phone" App to check on the wife.... and she's on her way home... so GoodLuck
Poor choice of Brands.... but thats another story.
If you mean, can you enter latitude and longitude coordinates on your GO 750 LIVE GPS device .... yes.
First you'll want to set your unit to accept coordinates. From the main menu, tap Change Preference, then select "Set Units" and select a Latitude and Longitude format in the "Coordinate display" screen, and then tap Done.
To navigate to a location using latitude and longitude coordinates, follow the steps below:
The Garmin nuvi's were designed as automotive navigators and not really designed to be used as marine or outdoor GPS units with the exception of the nuvi 550 which is an all around GPS. The Garmin handhelds are recommended for marine and off road recreational use but it is possible to navigate if you know the coordinates of your fishing spot. To enter coordinates: Touch Where to? > Coordinates and touch a box to enter a coordinate. You can also refer to the manual for more information. nüvi® 215
I would suggest that you go to a web site that will take those co-ordinates that you have, enter them and then get or have the program show you the other co-ordinates that you need and can use, Also you may want to check in the sub menu on the gps unit, sometimes some of them have the ability to switch to different co-ordinate system, but this is sometimes, not always. Hope this helps
Hi, Your GPS is accurate for that brand. I have a Lowrance I Finder Pro. We could both put in the same coordinates and come up in different locations. It is just the way the different GPS's get their signal from the satellite. I use my GPS most of the time for a sport called Geocaching and so when I am given coordinates and don't find the thing I am looking for I so about a 30ft-60ft search around where my GPS took me. So yours is basically doing the same thing. I wouldn't worry about it......it's just the way the different models receive the signal that thows them off a bit. If you went out and got a set of coordinates and then I put those same coords into my GPS I would arrive at a completely different location as you. All is well....no need to worry.
Switch-on while holding the MARK key, this performs a master reset
and re-enter an initial position then leave it receive in full view of the sky (outside). This only needs
to be done once, but deletes all user data. The GPS can take 30 to 45 minutes to acquire. It worked for me on GPS 45, twice.
Are you sure you're using the exact same format on GoogleEarth and your GPS?
GoogleEarth: save the waypoints in a KML file (NOT KMZ) to your computer, naming it appropriately. Go to http://www.gpsvisualizer.com/gpsbabel/ and convert the KML file to a GPX file, using their converter. They will present you with a file to download. Download it and send those waypoints to your unit and you'll be set to go.
