I ordered a Time 2, lets see when it arrives.

A big use would be display for navigating on bike trips, hooked up to a phone that does the routing with a capable app.

I have found a few apps that kinda route themselves? I dont imagine that to be very good.

There is a single app to display Google maps output, which I think is similar to what I would imagine.

Osmand displays turn directions and distance in a notification.

That alone should be pretty easy to sync and display reliably?

Something with a minimap for visual feedback would be even cooler but likely not possible without deep app integration and the app itself communicating with the watch.

(OSMAnd has plugins so this should be possible, but someone needs to do it)
