Let me rephrase, I'm desperate for a more open, not garden locked solution. Paying for Garmin and tomtom is just paying for a different corporation locked solution.
It's the same way I'm desperate for a replacement for Plex. But the closest thing, jellyfin, is terrible. It fails to match media, fails to play back certain files, and a bunch of other issues that Plex just does not have. Despite that I have donated to the project, I want to get away from plex and support something open. I want to get away from Google and support something open. But I need to be able to have a minimum amount of functionality.
