I have just bought my fenix 6X. Love it. My previous Polar had a "Back to Start" data screen where it would show the direction to my starting point and distance (straight line). This was very useful when riding MTB or trail running as you just selected the screen and followed the arrow.
I see in navigation you can back track using actual reverse route or straight line, but it seems you need to get out of the activity to do that.
I find nothing simple like this on my 6X where I can just select a screen in my current activity. I know different makes use different solutions. Any suggestions?
