Hate to beat a dead horse here. But, it seems to me that converting a TRIP to a TRACK is not a practical solution to the problem of having the GPS (ZUMO) re-calculate a route that is different than what was originally created and downloaded. I under stand that a TRACK is simply a collection of co-ordinates and when viewed it simply overlays those points on a map. I believe there is no connection between the roads on the map and the collection of co-ordinates. Therefore, again my perception, I believe that after converting a ROUTE to a TRACK on the PC, downloading the TRACK to the GPS, then viewing the track on the GPS it will look exactly like what it did on the PC. However, it will not provide voice prompts for turn by turn travel. The GPS does provide on board capability to convert that TRACK back to a ROUTE however, it seem like that function uses only the start and end points and calculates what it determines to be the most efficient route depending on the navigation preferences established by the user, which again may not look anything like the original ROUTE. This brings us full circle back to the original problem. Where-as the older GARMIN devices would exactly duplicate a route as created on a PC when it was downloaded to the GPS without any modification. Wonder why they changed it? Or, perhaps it is my feeble mind that just cannot comprehend all this computer crap and I will just have to continue placing a plethora of redundant via points in my routes.
Sorry for all the verbiage here but I keep hoping that there is actually a light at the end of the tunnel and that someone out there can educate me in the fine art of programming a route on a GARMIN GPS.
I also have a love/hate relationship with Basecamp. I have tried many alternatives: Google maps, Harley Trip planner, Furkot, Mapquest and a few others I can't remember. All have serious deficiencies.
I find Basecamp to be the most capable and to interface best with my Nav V. Most issues with Basecamp are related to ease of use and lousy documentation rather than wholesale missing capability as with most alternatives. Although, I found one ridiculous bug just this week, although Garmin of course denies it is a bug.
I often start planning rides in the prior calendar year. I started planning my September 2018 Ireland ride last October. As in the past, I found very odd things when I loaded the routes into my Nav V. The routes would appear in random order rather than chronologically. And the categorization seemed random with some days showing as upcoming, some as scheduled and some as unscheduled. I think I got this correct from memory, but maybe not the precisely correct category names.
I saw the same behavior three years ago with my Scotland tour, but didn't take time to research it. Now that I am retired, I decided to dig into it. After two days of experimentation and emails to Garmin support, I think I found the problem.
I create my trips using Trip Planner. This organizes trips by calendar day which is logical. The problem is that each waypoint within each day's route also has a separate date. And this date seems to be completely independent of the day in which it is contained. I found that even though my trip dates all occurred in September 2018, the waypoint dates were a mixture of 2017, when I first created the trip, and 2018 for changes I made this year as we finalized hotels and such. It does appear that only the first waypoint each day needs its date to be manually changed to match the date of the Trip Planner day. Once I changed the first waypoint date to the correct 2018 date, the other waypoints in that day's route updated to match. Having done this for each day of my trip, things now seem to load into the GPS in chronological order and all days are now correctly categorized as upcoming.
When I mentioned this bug to Garmin, I got a response that Basecamp was not designed to plan trips a year in advance. What a pile of bovine excrement. This would affect trips planned only a month in advance if planning a January trip in December. I don't know why they simply can't admit they made a mistake and forgot to have waypoints inherit the date of the trip day into which they are inserted.
I am still not completely clear what changes a given day's route from upcoming to unscheduled and then to scheduled. And I have found no Garmin document or video which addresses it.
