Go to the Garmin site and download the POI loader utility and install it on your laptop. You will also need a USB cable to plug into your laptop and the Garmin unit. The USB cable is any old one that will fit. It plugs into the same place your power cable plugs into.
Here is the site for the loader

I don't have an FTP site so you will have to email me and I'll send you the files.
[email protected]
Save all the files to a folder that only holds these files.
Plug your Garmin into your laptop then run the POI loader utility and point it at the folder that contains the files and it will do the rest.
Now go to your Garmin after it's done and click on "Menu" then "Where to" then "My Locations" then "Custom POI".
You will then see a list like Flying J, Petro, TA and Pilot. You can click on any of those and it will show you the closest one or you can click on "All Categories" and it will search all of them and display the closest ones.
I also got the Blue Beacon GPS coordinates for truck washes. I'll search for Loves and other places in the coming days and plan to keep this up to date.
