Red Warning

Can it be disabled?

yes check the navigation->sharp bend warning

I would find the turn warning useful if it would pop up in due time instead of immediately at the beginning of the turn. Does anybody know how to adjust the time?

I get this warning message.  I have turned off the sharp bend warning.

I still get the message even though I have turned off the warning.  It is kind of useless as I never see it until  after I have done the turn.  I never see it before the turn, during the turn I am not looking at the GPS. I am looking at my surroundings during a turn.

Mine seems to give me the sharp turn ahead warning in advance of the turn.  I haven’t configured it so it must be using whatever is the default. 

I observed it closely during a ride today and on two turns, the warning showed up about 50ft or so after the turn, definitely not before the turn.  Of course I have the sharp bend warning turned off, so I should not be getting it at all.  Also one of the turns was a normal 90 degree turn, not sharp at all.  It seems rather useless to provide a warning after the turn.

Were you following a course?

I can confirm that this ‘warning’ only appears when following a course and is UNRELATED to the sharp bend warning (which I have turned off now). It pops up very close to the corner (as you would hope) and generally seems to be on flat or downhill bits. I don’t recall seeing it going uphill (a good thing) so it must be speed related. Did it make me slow down? No.
