Thanks for reply.
So in navigation mode its just the announcements defined in the config file and the display timeout of Locus, thats it, ok.
Currently I set it to 20|70 and a timeout of 10sec.
Besides that 20|70 is currently not the time Locus uses, it works well.
Around 20sec before the display turns on and you get a beep, so you can see, what to do next.
Around 5sec before the second announcement and with 10sec timeout the display is still on, when you do the turn.
Nice. Leave it like it is. Simple to use and customizable.
PS.: Test it by yourself on your bike holidays. Have a nice trip. Where will you go to?
