personnal information/messages during navigation

Alex_aco

Hello everyone,

I would like to know if it is possible to have extensions in a .gpx (extension), which will appear as text information on my system navigation.
For example, on some waypoints, I want the navigation system to show me the message "drive max. 75 km / h" or “stay in the middle line” or different text or illustrative information.

The question concerns how to program these kind of information by .gpx file or different way, so that I can program / request that information is indicated to us on defined location (waypoint) or during one section of the path.

I would be very grateful if you can help me.

Best regards,
Alex
