I will be very interested in if changing the points to not announce on my route last night allows it to be run a a single route instead of breaking it into two different trips. I don't know if you tried to do that after I logged off at 9:00 pm....
We did edit the route properties to change announcement. Except for the start, end, and test waypoint for sharp curve, all others were set to not announce. The route was recalculated and when transferred to the GPS it was one single route.
During the session Kevin mentioned 29 points being the maximum, but he emailed later after looking it up and said he misinterpreted.
Below is context from his is is from the manual. While confusing and contradictory to other manuals, in the text Kevin pulled from his Nav6 "Via Point" is an alternate name for Waypoint. Based on this, the max number of waypoint is 29. Waypoints announce. Shaping points are what is generated when we "rubber-band" the route using the insert tool in Basecamp and it drops the small black dots. There can be up to 125 shaping points between waypoints. Shaping points should be set to not announce.
