Many thanks for the Spanish Aire POI's. Could you tell me what the KML files are. I have a TomTom One XL Europe and usually just have the BMP and OVL files to download. I know that I don't need to put the XML files on.
KLM files can be used in Google-Earth. I often use them in advance we leave, just to check if the places really exist and to have an idea how they look.
You can translate your OV2 files with a small program 'poi-edit' or 'poi converter' to KLM and others.
