My navigation prompts at almost every switchback on a tight gravel road. Is there a way (in the route creation, i would assume) to force my 130 to only tell me to turn where i tell it to tell me?
The device will only prompt in response to the cues contained in the course. You can edit (delete) these cues using software, but suspect that may depend on how you created the course?
I suggested RideWithGPS as it is what I use and am therefore familiar with.
