@jfheath, this discussion was started by me due to being surprised that Basecamp produced a different route upon recalculation of one shared with me that was created by the same Basecamp version and map. Different route preferences and avoidance would logically produce variations but I hadn't given that any thought until it happened. It surprised me not only because I hadn't though about it, but also because this fellow and I have shared routes many times and this is the first time I detected deviations.
Well yes - Garmin uses the route points as the fixed locations through which the route passes. In order to get from one route point to the next, it uses the preferences that have been specified - so as preferences change, the route between route points change. In the same way that the Zumo does when it receives a route. Although the Zumo keeps the original until it recalculates it.
The route preferences are specified
either in the Route Profile that has been used - typically Motorcycling.
Or - in the settings for just that route - if you have selected 'None' for the route profile. The advantage with this is that any changes that you make are shown immediately on the map.
It is possible to share your profile settings with another user - they are stored in the windows registry. I can expand on that if anyone wishes to have more detail. But I have yet to find out where custom route information is stored - probably in a different part of the registry.
Have owned Zumo 550, 660 == Now have Zumo XT2, XT, 595, 590, Headache
Use Basecamp (mainly), MyRouteApp (sometimes), Competent with Tread for XT2, Can use Explore for XT - but it offers nothing that I want !
