Garmin Foretrex Route Problem part 1

Описание: UPDATE: GARMIN ACKNOWLEDGES THE PROBLEM, BUT WON'T FIX IT.
Part 2:    • Garmin Foretrex Route Problem part 2  
My findings (on Foretrex 601 with firmware 3.90, but also apply to other Foretrex models):
1. Foretrex skips the 1st Waypoint when you Follow a Route, so the Route needs a dummy starting Waypoint (which will be skipped) as a work-around. Otherwise the Foretrex will skip the 1st navigation Waypoint, and send you to the 2nd navigation waypoint. This is a serious issue that needs to be fixed or at least documented by Garmin.
2. This Garmin documentation is erroneous: "6. Select a starting point for navigation."
Instead, select the Final Waypoint to Follow the Route (the lower of the 2 choices).
If you select the Start Waypoint (upper choice), Foretrex will reverse the order of Waypoints in the Route, and then follow the Route in reverse order.
This is a serious documentation error that needs to be corrected.
3. The navigation errors I encountered in troubleshooting appear to be due to processing lag in the Foretrex. When you make a change to a Route, give the Foretrex at least several seconds to process the change before Follow. Otherwise the navigation can be incorrect.
