I have a question regarding exporting gps files from MRA to Garmin XT2....and how the XT2 reshapes routes differently with the two file types.
My workflow is to create my routes using MRA on my laptop, then export them from the MRA app on my iPhone to Garmin Tread. This then automatically syncs the routes with the Garmin XT2 (which is a pretty cool feature).
I use named Via points, and quite a few additional shaping points to define the routes.
If I export to Tread using the gps 1.2 formate, then it appears that all shaping points are lost and the XT2 simply routes directly between the Via points - which basically loses all the lovely twisty roads I have lovingly crafted the route around.
The workaround is to turn all shaping points into Vias - but this is not a good solution as you then end up with loads of confusingly named Via points.
However, if I export to Tread as gps 1.1, then the routes come across normally with all the shaping points intact and the XT routes perfectly.
I have read somewhere on a Zumo users forum, that in the case of the gps 1.2 format, MRA actually does not export the shaping points, but instead sends many (hundreds?) "ghost points", (route extensions?). It appears that the Zumo XT2 ignores these completely.
Does anyone know if this is correct - and why it works this way?
I am currently just exporting using px 1.1 which works just fine, but I am intrigued as to why gpx 1.2 works this way and doesn't include shaping points?
