If you are trying to send a POI file to your 5200 (and I could be wrong about your intent) here you go. (If it's something different, let us know). Using the TomTom MyDrive web page, take a look at this part of the menu. You will need to have set up an account there, and also use the same email/password on your 5200. Once connected to the net, your 5200 will suck down whatever you upload to the web site in the way of *.ov2 files.
If, instead, you are looking for already-built POI lists, they are out there at sites like this and numerous others:
Free POI files - GPS POI Directory (GPS POI Zone). Points of interest and support for all popular smartphones, tablets, GPS devices and software. Road safety, recreational and corporate points of interest.
