This watch doesn't work

I purchased the Garmin Instinct solar a little while ago and I am extremely disappointed by its performance.

- I've tried many times to upload navigation routes from the Garmin Expore both from my laptop and from my phone. Yes, the route is uploaded but there is no route to be seen when I try to navigate it.

- When I hike following a navigation route the timer keeps stopping so there's no travel distance recorded or estimates for travel or arrival.

- When I do a return on the route there's no times or distances shown on the watch. The only thing that seems to work in regards to navigation is the arrow on the map.

What's wrong with this thing?
