If I start a course and I am 15km’s away and i select “don’t navigate to start” the 840 doesn’t tell you how long the route is or anything. The 830 used to advise how long the route was.
Also, if you tap on the screen and a box pops up saying “resume navigation” if you tap on that, it then navigates you to the beginning of the nearest part of the course, despite advising the 840 that I didn’t want to navigate to the start.
