I've used the watch to follow courses before which works ok. This morning I thought I'd see how the Navigation function worked by asking it to guide me to my work location. Interestingly the watch was able to find the building I work in as it's a POI on the map so I selected 'Go' and started the ~1k walk to get there. Maybe 12 mins later I arrived at work & the watch was still displaying the 'Calculating Route' spinning circle!
So my question does Navigation work & if it does how long might I have had to wait for it to come up with a 1k route?
