There is an Android and a companion Pebble app (“Nav me”) that reads the Google maps notifications (“In 300 meters turn left onto Jefferson Street”) and displays them on the watch. The remaining distance until the next navigation instruction decreases real time. Nothing fancy like minimap view, but can be useful in some situations.
Takes more effort and results in a static snapshot without being able to track the evolution of the project. (disclaimer: I don’t work with ai, but I’d bet this is the reason and also I don’t intend to defend those scraping twatwaffles in any way, but to offer a possible explanation)
