This is why the Ambit 3 attracted me. I was hiking at the weekend and went off trail, wasn't that confident where I was going and kept having to look at my phone and google maps which was a pain.
But am I right in thinking that you need to set the route map on the device that you want to follow beforehand? Maybe it's not very useful if you get lost? Or is it possible to see nearby landmarks or send a map on the go from your phone to the watch?
