Could you better explain this ?. Reason I'm puzzled is my Wahoo Bolt does do "turn guidance" in the sense that it will display in the data and map screens, in a text format, the upcoming turn, the distance to the turn and the street name. Seems that this would be defined as turn guidance, just no viewing it on a map. The Garmin units do a much better job (IMO) then Wahoo with on-map visualization of the turn, the distance, white direction arrow, etc..
It has "turn information" in the file that is loaded to it.
That's what the "course points" are. They work the same way (
basically*) as you describe they work on the Wahoo.
The Wahoo units keep track of the upcoming course point. The Garmins do too but somewhat incompletely.
* The labels for the "course points" are much longer on the Wahoo.
The "turn guidance" on the Garmins is not in the file loaded to the unit. They are, basically, "course points" generated (calculated) by the unit itself. The Garmins do a much better job displaying these calculated "course points" than they do displaying the "course points" in the TCX file.
