I don't know if it me or what but i had a problem last weekend.;
I set selected the coarse and set to ride using my 1040 for navigation. and my iPhone with headset and connect running in the background. (my normal set up)
For some reason the screen never switch for TBT instruction, and the w no voice prompt in the head set. i check and turn guidance was on.
I did get Climb pro when the time was wright and the corse point list if i scrolled to it.
I can think of any setting i could change or have changes other that recently installing update 16.11
Any ideas gratefully received.
