I have since today (11. February) the Forerunner 255 and dont know, how can it set to always on? Newest firmware on.
In the evening I have a dark display.
I ve set in every condition the backlight to "no timeout".
I look after 10 minutes to the display, dark!!!
Sometimes after 30 minutes, dark!
What is the trick, I could have an always on display?
If its not possible I will send it back.
