For me the watch is mostly for the recording and stats but the navigation is a little bonus. It works OK following a line but if actually get lost then I’ll stop, pull my phone out and look at an OS map on the big screen. It does work really well for running though
You do need good eyes. My are going now with age and it is a bit tricky without reading glasses. The watch is nicely customisable so I’ve put some more contrasting colours on and a bolder font to make it more useable.
I’ve never worked out if I can scroll the map and have no idea how to do that on the watch
long press on menu, then you can choose pan or zoom, then use the up/down buttons. Its not very nice use but is there in an emergency to get you back on track. The 7 has a touchscreen and this function is supposedly much better, but not enough for me to buy one
