If you see something you like, get back to us and we'll explain how to use TomTom's MyDrive site to transfer POIs to your 550. Most use the MyDrive website that TomTom provides.
Alternately, you could read the 550 manual.
Here's how most do it, using the MyDrive web site provided by TomTom (
https://plan.tomtom.com ) where you set up an account. You need to use the same account name and password on your 550 to link them together.
Importing a community POI list
You can find collections of community POIs on the Internet and upload them to My Places using TomTom MyDrive in a web browser. A POI collection might contain, for example, campsites or restaurants for the area you are travelling in, and provides an easy way to select a location without the need to search for the location each time.
Tip: Some TomTom Navigation devices have POI lists pre-installed.
Your TomTom Rider uses .OV2 files for POI collections.
Note: Your TomTom Rider needs at least 400 MB free space before it can import .OV2 and .GPX files. If you see the message You need more space, make space available by deleting unwanted .OV2 or .GPX files using MyDrive, or deleting device content, for example delete a map you don't use.
To upload an .OV2 file to your TomTom Rider, do the following:
1. In a web browser, log in to your TomTom account.
2. Select POI Files in the My Places menu.
3. Select Import POI File and browse to your .OV2 file.
Tip: The name of the places list in My Places will be the same as the name of the .OV2 file. Edit the name of the file so that you can easily recognise it in My Places.
4. Make sure you are logged in to MyDrive on your TomTom Rider.
Your TomTom Rider syncs with your TomTom account and receives the new POI file.
Note: Some .OV2 files are large and can take a long time to upload. Make sure that you sync your TomTom Rider before you start driving.
5. Select My Places in the Main Menu.
Your new POI list is shown in the Places list.
6. Select your new POI list.
Your new POI list opens showing all the POIs in the list. Select the map view to see the POIs on the map.
Deleting a community POI list
You can only delete an uploaded POI list from your TomTom Rider using TomTom MyDrive in a web browser.
To delete a POI list, do the following:
1. In a web browser, log in to your TomTom account.
2. In the My Places menu, select POI Files .
3. Select the POI file you want to delete, then select Delete.
4. Make sure you are logged in to MyDrive on your TomTom Rider.
The POI list is removed from your My Places list.

The Rider also apparently supports an additional interesting approach to this using a memory card, per the manual:
Using community POI lists
You can find collections of community POIs on the Internet and use them by saving them to a supported SD card that you insert in the device. A POI collection might contain, for example, campsites or restaurants for the area you are travelling in, and provides an easy way to select a location without the need to search for the location each time.
Tip: Some TomTom Navigation devices have POI lists pre-installed.
Your TomTom Rider uses .OV2 files for POI collections.
