removal of poi files

You have to move a file from the mac desktop icon/drive that represents the device, then delete it...as the mac OS creates a 'Trashcan' folder on the gpsr that its OS will still see as a viable file.

Thanks Keith.
I'm not sure what you mean by creating a trashcan folder. Do you mean the OS will create a trashcan folder within the icon? Just moving the file to the trash has no effect on the gps.

Creates a folder on your GPSr that is the same as the trashcan folder on your Mac's HD, and files 'deleted' or moved to the trashcan from the desktop icon on the Mac go to that folder on the GPSr. The GPSr's OS does not know that the folder the Mac OS created on the GPSr is a trash folder - and when it boots up, it finds all files in that trashcan, and loads them anyway...to get rid of a file from a GPSr using a Mac, you have to move the file from the GPSr to another storage location, then delete it from the second location.

At least that's how I understand things work with Macs - and someone will come along soon and tell me I'm smoking my socks....and tell us both how it works.

I removed a jpeg from the folder that I added, but it's still in the gps when I boot it up. Must be something I'm missing.

As Keith has indicated, when you delete something from your GPS unit while it is connected to your Mac, the Mac creates a hidden trash folder. You need to do a global search to find it. And then you need to empty it in order for the deleted file(s) to go away.

I think Argyle has a nice bouquet...

On a Mac if an item from a connected external device is thrown in the trash it will be deleted if that device is still connected when the trash is emptied.

I make changes to a master POI folder I keep on my Mac's Document folder. When I update the GPS using POI Loader the POI files I no longer want are overwritten. A new poi.gpi is installed in its place.

The latest POI Loader for Mac does have "remove all previously installed POI" option after selecting the device for updating. Be sure you are using the latest version:

If that doesn't work for you, you could create a dummy POI folder on your Mac that is empty and try to update the GPS from that folder. I don't know if this would work.

I don't think you need to look for the hidden trash folder (oddly called .Trashes) because I found that the folder was 0kb in size after emptying the Trash can while the nuvi was connected.

I just spent a while figuring out the same thing...

to clear pois via mac.

1. Mount GPS as a drive.
2. Open garmin drive.
3. in finder window- search for poi.gpi
4. Delete all poi files
5. Then EMPTY TRASH
6. Eject GPS and everything should be gone...

hope it helps,

I have a Garmin 260 and I just had to return it and get another one because it was frozen. Has this happened to anyone yet? If so, what have I done wronr? I have a folder called my POIs and I have all my POIs and BMP files in the same folder. When I download POIs and bmp files I do it manually. Does everything reenters my nuvi again? I am confused about this. Help please!!

That says it all, "I just spent a while". The key was emptying the trash, thanks, Kyle. Spend enough time with this and it falls into place. Wish there was a switch to toggle between computer and solo operation.
