Edit coordinates (of favorites in nuvi)

Will POI EDIT or Map Source help do what you want to do?

First connect unit to computer and make a copy of the current.gpx file in the Garmin GPX folder.

The easiest way to do it is to use Extra Poi Editor http://turboccc.wikispaces.com/Extra_POI_Editor .Click on file and select Open Garmin Favorites.Once the favorites come up double click on the one you want to change.You can manually change it by putting the correct coordinates in and click OK at bottom.You can also move the marker on the map by holding mouse button down and putting in the correct location.Then click on grab top left and the coordinate will change in settings boxes.Again click OK at bottom.Once completed click back on file and select Save to Garmin Favorites.If by chance they do not transfer correctly back to gps.Take the copy of the current.gpx you made and rename temp.gpx and paste it back to the Gpx folder and it will update the current.gpx.

I use Extra POI Editor. It's easy and works great. When modifying your favorites outside of your GPS you have to delete all stored favorites from your GPS memory before restoring the modified file. Otherwise you'll have duplicate entries.

I recently noticed that I can't restore my backup favorites if I don't name the file current1.gpx. I used to name it temp.gpx in past and it worked, but since the latest firmware update it doesn't let me use this or any other name except current1.gpx.

I own a 1250t with firmware ver. 4.60

The methods mentioned above assume you have access to a PC. You can use the following method to change the coordinates (actually create a new favorite with the correct coordinates) of an already existing favorite directly on the unit.

1. Place the GPS into "GPS simulation mode": Tools>Settings>System>GPS Simulator ON

2. Find the desired favorite you wish to change using Where To? and display it on the map. Now use the "Set Loc" button to set the unit's location to that favorite's coordinate

3. Back out to the Where To? screen, select Where To? and select "Coordinates". The coordinates listed will reflect your current location which is also the location of the saved favorite you wish to change. Simply enter the correct coordinates and save the new coordinates as a new favorite with the corrected coordinates. After saving, the old favorite with the incorrect coordinates can be deleted.

Good point DorkusNimrod I have used that method also but you can't put the address in when you edit.Just the name and phone number.I emailed Garmin a while back that you should have that option to add all information.As they say they will push it up the line to be looked at.

One other thought.I have a 265.When you send a favorite from Google,Mapquest and Bing Maps it will put a file next to the current.gpx.It is usually a number with gpx.Once you boot up the gps it is loaded into the current.gpx file.Then it serves no purpose except to take up space.If you have not deleted it load that file outside the current.gpx to Extra Poi Editor and make changes as outlinded above.Delete the orginial favorite from the gps.Save the file from EPE as gpx.Paste back in the GPX folder.re-boot and it should load to the current.gpx.I delete these files once they are loaded to current.gpx.

This is where Garmin is giving everyone a snow job. The street pilots made it easy to edit anything in an existing favorite. Garmin dumbed down the Nuvi line because as a tech rep told me people thought the menus were too complicated on the street pilots. Now as they told one poster they're thinking about putting that feature back. With my 2820 all I have to do to edit anything in a favorite is go to tools, my data, favorites, edit/review favorite, how much easier can it get? I can do so much more with the SP including editing what information appears on the screen. I find the menus much more complicated with my 855. The only thing I can say my 855 has over my 2820 is a bigger and brighter screen. It's too bad Garmin doesn't take the features of my 2820 and the screen from the 855 and make a new gps line, I'd buy one in a heart beat. Well guys, that's my rant for the day.

Thanks for each of your comments. Yes Extra POI Editor will work but I was looking for a way to do the task right on the GPS without using a computer. I'll give the simulation mode a try and see how that works.

Seems like editing coordinates is a reasonable option to expect.

That would be bad marketing - if they created the perfect GPS, then we would all buy one and never have to buy another nuvi again!

Today I wanted to make a modest change in the position of an old favorite I had moved from previous GPS units to my brand new 3790LMT. On most of my previous units, if you could place yourself and the GPS at the desired revised location, you could just select the favorite somehow (we called them waypoints a while ago also), and use a menu option to replace the favorite's current coordinates with those of the current position--often including an option to average for a while to get better accuracy.

I was horrified not to find any way to do this on-unit on the 3790LMT, and horrified to find this thread which suggests that at least a while ago other current Garmin GPS units also did not let one do this directly. As an exercise I used the "where to--coordinate--then create a waypoint at that coordinate" method, somewhat along the lines suggested by Dorkus Nimrod above--but this is a lot of trouble compared to the old.

Has anyone a better way for a 3790LMT on 4.90 software? Or do people wishing to do several of these generally do it off-unit?

I attach the GPS to the computer and then open up the favorites gpx file using EPE. I make the change using EPE (move the marker) and then save it back to the file. It will make a new favorite and put a "1" after it. Such as "Home1". I then go in to favorites on the GPS and delete the 1st one and then rename the new one.

What file contains these favorites?

current.gpx in the Garmin folder?

Yes. Current.gpx

My NUVI40 will make a favorite of where ever you are. Bring up the map, press your vehicle icon, then save it. If the name already exists, it puts a '1' on the end of it.

I may have misunderstood, but I was under the impression that pwohlrab implied he saved the file back to the GPS.

I suspect that pwohlrab left out a step or two.

One can edit current.gpx by whatever method one prefers but I thought that to get the change to take effect the old current.gpx file needs to be renamed to [anything other than current].gpx and put back into the [nuvi]:\Garmin\GPX folder.

EPE can receive favorites and send them back. I would just change the coordinate and send back to GPS.

And then saved it back to the gps. It sticks a 1 after the favorite name. It does not over write the original. You wind up with 2 favorites. One is the original and the 2nd is the corrected one. You delete the original and then rename the corrected one.

I had always understood that you could not edit current.gpx because it was an OUTPUT only file. Indeed, Gary Hayman says in
http://home.comcast.net/~ghayman3/garmin.gps/page15.htm

"As you add Favorites, either by hand or by other program or WEB techniques, the nüvi's internal Favorites and later, the "current.gpx" file gets updated.

This file is a one way mirror of what is contained in your unit as your Favorites of the time (and your Active Track [or Trip] log information). It is a copy (repeat copy -- which only goes one way) of what your nüvi has as it's Favorites. It is important to understand that it does not influence your instrument in any way, as long as it is named "current.gpx" -- as such, it is ONLY a repository of the inside the nüvi's information of your Favorites. You cannot make changes to that file and paste it back into the nüvi's directory expecting that you are doing some sort of editing, for it will immediately be erased upon startup and replaced by what the nüvi has as it's Favorites."

In one of my later backups, I have a GarminDevice.xml file which contains the following.

<File>
- <Specification>
<Identifier>http://www.topografix.com/GPX/1/1</Identifier>
<Documentation>http://www.topografix.com/GPX/1/1/gpx.xsd</Documentation>
</Specification>
- <Location>
<Path>Garmin/gpx</Path>
<BaseName>Current</BaseName>
<FileExtension>GPX</FileExtension>
</Location>
<TransferDirection>OutputFromUnit</TransferDirection>
</File>

HOWEVER, I just did what charlesd45 and pwohlrab indicated I could do. I connected my unit to the PC. I used EPE to make changes by moving the marker; saved the file; safely disconnected the 765T; fired up the nuvi and there were the new favorite with a 1 following the old name.

I then connected again. This time I edited with Notepad (in which it is really hard to find what you want). This time I changed the first number in lat and saved the file. I safely disconnected and now I had a new favorite with a 2 after it.

Then I connected again. Using Notepad again, I changed the first number in lon and saved the file. I safely disconnected and now I had a new favorite with a 3 after it.

How long has this been possible?????

Don't know the exact date but it has been a long time back.

We are never to old to learn, huh Jgermann? I have been making minor changes at least 2 years on my 1350 and before that my 650. How long before that...no clue.

I too make changes to current.gpx, and they always take without changing the name of the file.

Since Garmin tells you to make a secondary copy of current.gpx and erase the original before doing a hard reset, it stands to reason that current?.gpx. is read from upon bootups.

"
1. Connect the nuvi or zumo GPS unit to the computer
2. Go to the Start menu on your computer
3.Double-click My Computer (Computer if using Vista or Windows 7)
4.Right-click the Garmin/nuvi drive
5.Click Open
6.Double-click the Garmin folder (Skip this step if using a nuvi 1000 series unit)
7.Double-click the GPX folder
8.Right-click on Current.gpx
9.Click Copy from the right-click menu
10.Right-click on any blank area on the desktop
11.Click Paste to put a copy of it on your computer's desktop
12.Right-click on Current.gpx on your computer’s desktop
13.Click Rename
14.Rename the filename to something other than “Current” (For example, “Current1.gpx”)
15.Right-click on the renamed file (Current1.gpx in the example)
16.Click Copy
17.Right-click the Safely Remove Hardware icon located in the system tray
18.Click on the Garmin Mass Storage mode device if necessary
19.Disconnect the device from the computer"

Based on everything I have read here and elsewhere, my understanding was that current.gpx is an OUTPUT only file. That would be consistent with the above Garmin instructions saying to rename the file to "current1.gpx" (or with the many threads on this site recommending temp.gpx as the new file name)

However, I have been testing making changes and all my tests imply that a current.gpx file with a file time later than the file time of the previously read current.gpx (at previous boot time) will be read and (apparently) merged with the favorites in protected memory. I say this because entries that exist will be give a suffix number that will be incremented if you do it again.

I did the changes with EPE as many have indicated.

I did changes with Notepad (and it helps to turn on "word wrap")

Each time I copied the file to my pc, made a change using Notepad and saved the file on the pc. I then copied it to the [garmin nuvi]:\Garmin\GPX folder; safely disconnected and looked to see if the change had been added and it was.

I then did a test of file time. I have a "portable" freeware package called "Newfiletime" that I used to make one of my just changed files have an earlier time. When I copied that file back to the 765T; safely disconnected and looked at whether the change had been made, I found it had not been made.

I then took that same file on my pc and used Newfiletime to make the time on that file current; I put that file on the nuvi and the change was then taken.

You can get Newfile time at
http://www.portablefreeware.com/index.php?q=newfiletime

I still do not understand this. I will need to direct Gary Hayman to this thread.

@DorkusNimrod Golden!

cool. thank you
