Can't find the File?

Try moving the file to to an actual folder on the local drive, c:\ drive.

Also you may want to try installing the very latest version from the Garmin website. Uninstall the previous version first.

Last thing, the POI Loader does not actually see the file only the directory it is located in.

So create a folder call POIXXX or something and point to that folder.
TRY THIS FIRST.
Good luck.

Should be:

C:\Users\(your username on your computer)\Desktop

I'll answer your last question first. No you can't just copy the file to the SD card. You need to load it with POI Loader.

So, let's check a few things. Make a folder on your PC that contains your POI file(s). When you run POI Loader, and the screen comes up that says to select the directory that contains your data files, select that directory. Follow the prompts and the POIs will be loaded. Note that POI Loader will not show you or allow you to browse to the FILE. You need to select the DIRECTORY.

Exactly what Motorcycle Momma said, it only points to the directory the file is located in.
Make sure it is the only CSV or POI file in there.

A great big thank-you to Victor, Keith and Motorcycle Mama! I was looking for the FILE instead of just the DIRECTORY. It works! Thanks again, you guys really came through! Pure Genius!
