The basics

What brand and model GPS receiver do you have?

On my Garmin Nuvi 660, they appear under Extras and then Custom. You cannot add your own icon to the Nuvi screen.

It may be different on other makes/models.

When you download Custom POI files from this site, they end up in a folder on your computer. You will want to put all the Custom POI files that you want to load on your unit into the same folder.

You can create subfolders under the main folder and those subfolders will create categories on your unit. You can't have more than one level of subfolder. The files themselves will create the subcategory.

For example, it might look like this.

> My POI (Main folder)
>> IHOP (subfolder)
... IHOP.csv
... IHOP.bmp
>> National Parks (subfolder)
... National Parks.gpx
... National Monuments.gpx
... National Recreation areas.gpx
... National Parks.bmp
... National Monuments.bmp
etc.

In this example, IHOP and National Parks show up as categories and then under National Parks, the subcategories of National Parks, National Monuments, and National Recreation Areas show up.

Here are some screenshots of what it would look like.

This is a shot of the folder and files on my computer.

This is how the first level shows up on my Zumo.

When I select the National Parks category, this is what I get.

Then if I select National Monuments, I get this.
POIs

Then you need to use POI Loader to load them onto your unit. They won't be with the built in POIs but will be in a separate section as indicated above, mostly likely in "Extras".

You can associate a custom icon with your Custom POI files if you want. Click on the icons link at the top of each page and you will find the icons. If you scroll to the bottom of that page, you will find instructions on how to properly name and locate them so that they load to your unit.

Very cool with the sub folders! I'm going to do that myself.

It works very well.
