Inspired by the sky-runner’s post I ran a navigation test on my local trail (Vertical 1, FW: 2.50.28).
I planned the route with six Waypoints (WP). And there are four “Out-and-Back” (OaB) sections.

The Navigation has 3 features: Showing the Direction, Distance to the next Waypoint, and the Climb Guidance.
Showing the Direction: Worked well during the whole run, and it was always pointed to the right direction, as You can see in the photos.
Distance to the next Waypoint: This was inaccurate on all OaB sections.
OaB1: It showed the correct next WP (WP2), but the distance was calculated using the turnaround at WP1 (which I had already passed) rather than the remaining direct distance.

OaB2: Although the direction was correct, as I was approaching the sharp turn the watch suddenly began showing the distance to the previous WP (WP4) . The distance continued to increase until I actually made the turn, at which point it corrected itself to WP5. In this case, it wasn’t even a full OaB—just a very sharp turn.

OaB3: Again, while the direction was right, the watch showed the distance and icon for WP2, even though WP6 was only 200m ahead of me. It only switched to WP6 when I was 25m away.

OaB4: On the way back, the watch displayed “A,” meaning it had “auto-reversed” to the start instead of the “B” finish line.

Climb Guidance (WP zoom): This failed on OaB sections too. It consistently showed the previous section, making it look like I was moving backward on the elevation profile.
OaB1: Running uphill from WP1 to WP2. Upon reaching the WP1 turnaround, the CG initially showed the correct upcoming profile (WP1 - WP2), but after 50m, it reverted to the previous profile (A - WP1). It seems the “auto-reverse” feature is interfering here.

OaB4: Running downhill to finish. I even got the notification for steep downhill section. But the watch showed the A - WP1 profile.

(Today I tried the Navigation on other trail, and the CG “auto-reverse” happened every time I’ve been on OaB section)
(Side Note: I wore Coros Pace 3 with the new “Pace Strategy” and “Hill Alerts” on the other hand, and it handled all WPs and OsBs w/o any issue…)
