Add my own POI (Waypoints)

This is correct that’s one of the challenges. There are ways to do this in a URL as well, but it’s a bit more tricky :slight_smile:.

Also GPX has no real standard for colors or symbols. AFAIK, these are just random text that might be understood by some navis and might not be understood by other navis.

The GPX Spec states:

Text of GPS symbol name. For interchange with other programs, use the exact spelling of the symbol as displayed on the GPS. If the GPS abbreviates words, spell them out.

AFAIK, there is no standard way to specify the color in GPX.
