Vivoactive 3 - Road Map

Hello, 

I need some help with my Vivoactive Music 3. Indeed, when I create a road map on Garmin Connect Website for a running activity, it's written that's it's impossible to send to the watch.

Is Vivoactive Music 3 compatible with this function ? I found some websites saying yes and others saying no so I would like have more information about this problem. 

Thanks in advance and stay home :)
