How do they work on Wahoo? I’m not sure why you bring up route planning but the segment feature on the 830 does not really have anything to do with Strava route planning. On my 830, I simply have to “star” a segment on Strava and then Garmin will show me the segment data screen when I’m approaching it.
I had a Wahoo a while back and I remember it working the same, with the 830 having much better on screen visuals.
